Astro Boy: Omega Factor - Strategy Guide (Page 03)

Below are the cheat codes, hints and help for Astro Boy: Omega Factor - Strategy Guide (Page 03).

            You can get some small hearts and one big heart. If you
       are having problems accessing this area, make sure you're beside
       the C-shaped disc. Jump up and then jet downwards. You'll end
       up at the bottom of the screen. The monster actually attacks.


            At the top of the pyramid, destroy the second door of
       the Marine Express to meet Don Dracula again. This will give
       Astro another power-up. Proceed towards the right to go to the
       next stage.


       Stage 6-4 Ancient Prince Sharaku
       ---------
       Character: Rock

            Just like what the stage title implies, Astro gets to
       challenge Sharaku in this stage. It's Sharaku's pyschic
       powers against Astro's 100,000 horse-power. This will be a
       "hovering" shooting boss battle. Sharaku has several attacks
       and they are:

            Spear - Sharaku uses his spear to stab Astro. He can
                    also summon several spears that will lock on
                    Astro's current location.

           Aztlan - One of Sharaku's summons. Take note that the
                    spear Sharaku throws while summoning can hit
                    Astro. Anyway, Aztlan attacks using fireballs
                    from the jewels that lines its body. These
                    fireballs always go down. You can just go over
                    Aztlan and you won't get hit. You can also
                    destroy the jewels to prevent it from using
                    the fireballs.

          Mictlan - One of Sharaku's summons. Mictlan leaves some
                    ice crystals at its path. To stop Mictlan
                    from leaving those crystals, destroy its tail.

        Atonatiuh - When Sharaku moves his spear in a circular
                    pattern, he will summon rocks to rain down on
                    Astro. Take note that Sharaku is invincible
                    during the entire attack animation. The rocks
                    are easily avoided since you can already see
                    where it will appear before it completely
                    materializes.

            The best way to start the fight is to use the machine
       gun. This will prevent Sharaku from using any of his attacks.
       Spam the finger beam, arm cannon and the machine gun.


            After defeating Sharaku, he'll inform Astro that Pook IS
       his trump card. He'll mention about a certain secret of the
       HOA KABARI KILUMA potion or whatever that is. You'll learn about
       this later. After three months, preparations to return to the
       future has been finished. Astro explains to Wally that Sharaku
       has this ability of altering space and time.
 

             Rock decides to stay and help find a solution to prevent
       the Mu Empire from sinking. He thinks it is the best thing to do
       since Rag will do an excellent job in the present. Good luck,
       "President" Rock! You'll get Rock for the Omega Factor and the
       stage ends.



  Chapter 7 "World's Strongest Robots"
  ---------
  Summary:      Since Astro and Wally travelled in time and altered
           certain events in history, what would happen to the time
           they originally came from? The robots have gone on a rampage
           and Astro needs to defeat the strongest robots in the world.

       Stage 7-1 Versatile Robot: North
       ---------
       Character: North

            Upon returning to the present, things have gotten so
       different. It seems that five years had already passed since
       Astro and Wally disappeared. A huge robot will introduce
       himself as Pluto, one of Shadow's followers. He informs Astro
       that Shadow is waiting for him. Shadow informs Astro that 80%
       of the world has been destroyed because of the fighting. The
       robots and humans started fighting after the assassination of
       President Rag. As any villain would tell you, you need loyal
       followers to get the job done. He introduces the world's
       strongest robots: North, Denkou, Brontus, Epsilon, and Pluto.
       Shadow wonders if the 100,000 horse-power of the legendary hero,
       Astro, will be able to stand against his psychic powers. Could
       it be that Shadow is really...?


            Astro first challenges the all-purpose robot called North.
       During the first part of this battle, North will just
       float while using his hands to block Astro's punches. If Astro
       uses the arm cannon or a combo attack, North will counter-attack.
       To defeat North, jump and punch him once. This will make North
       raise one of his hands to block the attack. When he does this,
       you can either:

            a. Air dash towards the open side and punch him.
            b. Use the machine gun followed by the arm cannon.
            c. Use the finger beam.

            This fight will probably take some time if you don't use the
       arm cannon. When North receives enough damage, he will show his
       six different arms.


            Time for round two. North will now attack or defend
       using one of his arms. The arms, from the upper-left, counter-
       clockwise, are:

            Missile Launcher
            Shield
            Driller
            Self-Destructing Enemy Launcher
            Beam Cannon
            Blade Launcher

            You can now use the arm cannon in this fight without worrying
       of a counter-attack. Start the fight with a machine gun and this
       will stun North. Proceed with an air combo and finish it with one
       of your super moves. Repeat until you defeat North.


            You will get North for the Omega Factor after the fight.
       Power-up any of Astro's stats and proceed to the next boss,
       Denkou.


       Stage 7-2  Invisible Robot: Denkou
       ---------
       Character: Denkou

            Denkou is the second boss of this chapter. Denkou's only
       form of attack is his time bombs. Combo him and make sure he
       is not able to use his optical camouflage. In case Denkou had
       the chance to become invisible, you need to hit the sensors
       located on the different platforms. During the first time Denkou
       becomes invisible, you need to hit one sensor. The second time,
       you are required to hit two. And three sensors for the rest of
       the battle.


            At the start of the fight, immediately use the machine
       gun attack to stop Denkou from running away. Combo him and
       make sure you end it with the machine gun. Repeat until you
       defeat Denkou. You can defeat him in less than 20 seconds.


            You'll get Denkou for the Omega Factor. Upgrade any of
       Astro's ability and proceed to the next battle.


       Stage 7-3 Armored Robot: Brontus
       ---------
       Character: Brontus

            Your next opponent will be the armored robot, Brontus.
       Brontus has three forms of attack. He either bounces around
       the stage, transform into a spiked ball, or fire two to three big
       projectiles from his chest. Just like what his name implies,
       Brontus boasts his defense. He is only vulnerable when he
       shows his weak point, his core found on his chest.


            Basically, you need to evade his attacks and wait until
       he shows his weak point. When the core appears, attack with
       machine gun to stun Brontus. Use a combo attack and end it
       with the arm cannon. The length of this battle will really
       depend on Brontus.


            Anyway, you'll get Brontus for the Omega Factor after
       you defeat him. Power-up any of Astro's abilities to proceed
       to the next stage.


       Stage 7-4 Quantum Robot: Epsilon
       ---------
       Character: Epsilon

            You'll fight Epsilon in an environment similar to the
       moon stages. Under the water, Astro can jump higher and fall
       slower. Epsilon has four attacks and they are:

            Dolphins - Epsilon summons dolphins to attack Astro.
                       You cannot kill the dolphins. Just dash past
                       them and try to hit Epsilon while the dolphins
                       are still on the screen. Getting hit by a dolphin
                       will bring Astro to the other end of the screen.

             Urchins - Epsilon summons urchins to attack Atom. You 
                       can destroy the urchins using the finger beam
                       or any of your EX moves. Or simply dash past them.

               Whale - Epsilon summons a whale to attack Astro.
                       You cannot kill the whale. Just stay at the
                       bottom of the screen and wait until it
                       leaves.

         Photon Beam - Epsilon uses her photon energy to attack
                       Astro. She will try to lock-on Astro's current
                       position. See those cross-hairs at the bottom
                       of the screen. Anyway, land on the floor and
                       move a little bit to evade the beam. Take
                       note that the initial energy discharge can
                       damage Astro. Do NOT attack Epsilon when she
                       is attacking with the photon beam. Standing
                       underneath the beam can take away all your
                       life points.

            The best way to defeat Epsilon is to use the machine gun
       at the start of the fight. Go behind her and perform an air
       combo. Staying behind or underneath her will make Epsilon go to
       the other side of the screen. While she is moving away, you can
       hit her with one or two arm cannons. Dash after her and repeat.
       When Epsilon waves her hand, she'll perform a summon attack. Dash
       away from her immediately.


            After defeating Epsilon, she'll be added to the Omega
       Factor and Astro gets another power-up.


       Stage 7-5 World's Strongest Robot
       ---------
       Character: Pluto, Phoenix

            Pluto is the last of the world's strongest robots. He
       also happens to be Zoran's friend. Anyway, Astro still needs
       to defeat him to save the world.


            Pluto has several attacks. His primary attack is the
       spinning attack. He is completely invincible during the
       attack animation. Getting hit with this attack, Astro will
       be knocked back towards the end of the screen. He can also
       perform a ramming attack on Astro. His other attacks are:

            Missile - This will lock-on Astro's current position.
                      Avoid these or use your super moves to
                      destroy them.

              Laser - When Pluto charges purple energy on both of
                      his hands, he's preparing to attack with the
                      laser beams from his horns. Dash past Pluto
                      and combo him from behind.

               Fire - When Pluto charges red energy on his raised
                      hand, he's preparing to set the floor in front
                      of him on fire. Dash past Pluto and combo him
                      from behind.

            As always, use the machine gun to stun Pluto. Make sure
       to also use it when Pluto ends his laser/fire attack or when
       he lands on the ground. When Pluto performs the spin attack,
       Astro will be sucked towards him. Hold the opposite direction
       on the d-pad. Anyway, this battle will be longer compared to
       the other boss battles. Alternate between the machine gun and
       the arm cannon to deal damage.


            After the battle, Pluto will be added to the Omega Factor.
       Power-up any of Astro's abilities. Shadow cannot that believe
       that Astro defeated all of his robots. Anyway, enough with
       the disguise. Shadow reveals his true identity and he is
       *GASP* Sharaku. He tells Astro that Astro's dream of a world
       where humans and robots live together is an impossible one.
       The world needs an almighty leader to rule the humans and
       robots. Guess who? Our hero refuses to believe what Sharaku
       has said. But Sharaku tells him all is lost and points to
       the "Death Mask" orbiting the Earth. This satellite destroys
       robots and Sharaku will be able rule the world. In short, our
       hero failed to save the day.(;_;) BOO!


            After the credits, the Phoenix will appear and revives
       Astro. The Phoenix gives Astro one more chance to accomplish
       his mission. Since Astro already knows what is going to happen,
       he should have an advantage over his enemies. Think of the
       game you just played as a dream sequence.


            We then see a silhouette of a boy and a girl talking near
       a spaceport. The girl is sick and she needs to be hospitalized.
       Her father is looking for the world's best surgeon, Black Jack,
       to perform the operation. The boy promises her that he will be
       by her side when she is being operated. The girl tells her that
       only robots are allowed inside the operating room. The boy brings
       out his robot helmet and tells the girl that he can enter the
       room wearing his costume. Anyway, the boy invites her to go to
       the moon when she gets well. The girl's name is Prime Rose, the
       boy is Daichi. DAICHI?! *points at the walkthrough for stage 3*



            It's time to start the 'Rebirth' play. The stage select
       will now be available. You need to replay the game to see the
       other characters and the true ending. Don't worry, Astro keeps
       his power-ups during the 'Rebirth'.



  Prologue - Rebirth
  ------------------
  Character: Dr. O'Shay

       In case you have skipped this part during the first run of
  the game, please select stage 0-1 at the stage select screen. Do
  not press START. Doctor O'Shay will give Astro(that's you)
  some basic instructions. He'll teach you about movement and the
  attacks. I repeat, do NOT press START during this "review".


       After the training, walk over to Dr. O'Shay and Astro will
  ask him about Doctor Tenma. Dr. O'Shay will be surprised about
  this since Astro has just awakened. (Told you the events will be
  different.) He has no choice but to tell Astro what he knows. Tenma
  was the former head of the Ministry of Science -- the agency he is
  now heading. Dr. Tenma's only son, Tobio, died in an accident.
  Using the resources of the ministry, he made a super robot in the
  likeness of his son. But the robot was not able to grow and be like
  his son. Dr. Tenma abandoned "Tobio" and Dr. O'Shay found him
  and named him Astro.


       Dr. O'Shay tells Astro that Tenma's old house is found in
  Metro City's suburb area. Hopefully, Astro can get new information
  that will help him. Stage 0-5 will now be placed in the Stage Select
  screen. Wato, Dr. O'Shay's assistant, will be carried away by a group
  of robots.



  Chapter 1 - Rebirth
  -------------------

       Stage 1-1 Metro City
       ---------

            The stage starts with Astro in Metro City. Upon landing,
       Astro will see the bad guys leave the screen with Wato. Take
       note that these bad guys are the generic enemy fodder.


            This is a straightforward stage. To advance, you need to
       defeat the wave of enemies that will appear in the screen. At
       the first screen, you can break the glass at the background
       to get additional points. After defeating the first set of
       enemies, walk towards the right and meet a new character.
       He is Drake and he is a member of the World Federation. Drake
       is known for his antirobot stand. He will be placed in the
       Omega Factor but you still need to do some important events
       later in the game to get his face colored.


            At the end of the stage, Atom can collect a heart that
       will recover lost life points.


       Stage 1-2 World Federal Building
       ---------

            At the first screen, you need to destroy the traffic
       robot. This will stop the vehicles from appearing and will now
       let you advance in the stage. Destroy the upper-right glass of
       the building in case you still have not met Alejo. At the end
       of the stage, a heart should drop from the sky.


       Stage 1-3 Warehouse Battle
       ---------

            Use the same strategy you used from your first play. You
       do not have to defeat all the enemies in this stage. To finish
       the stage, you just need to go to the upper-right part of the
       warehouse.


       Stage 1-4 Spider Robot
       ---------

            The enemies and their attack patterns remain the same.
       The stage starts off with small spiders followed by the big
       spider robot. To defeat them, just perform air combos. Use
       the arm cannon to finish the big spider robot faster.


            After defeating the boss, walk towards the right and
       meet Wato. Wato will mention her Uncle Boon. Boon is an
       archeologist who is excavating ruins of the Mu civilization.
       His current site is in the Pacific Ocean region. Stage 0-4
       will now be added to the Stage Select screen. Astro needs to
       go to Cruciform Island but he must defeat the Magnamite first.


       Stage 1-5 Magnamite
       ---------

            The Magnamite and its attack patterns remain the same.
       Use the same strategy you used to defeat it during your first
       play.


            After defeating the boss, Astro gets to meet the robot
       responsible for all these. Before he even gets a chance to
       introduce himself, Astro calls him by his name and tells Atlas
       to stop. This surprises Atlas and he finds it amusing to meet
       another strong robot. Atlas escapes and tells Astro that they
       will meet again. We then get a view of Metro City with a man
       who was watching Astro. He is glad that Astro exceeded his
       expectations. In case you still can't figure it out, the man
       above Metro City is Dr. Tenma.



  Chapter 2 - Rebirth
  -------------------

       Stage 2-1 X Point, Pacific Ocean
       ---------

            The stage starts with Drake giving a speech regarding the
       incident from chapter one. He tells everyone that the robots
       are dangerous, using the Magnamite as an example. He asks the
       people to support his plan of banishing all the robots from
       the Earth. But Duke Red doesn't approve this and explains that
       the rampaging robots issue was just an accident. Drake rebukes
       Duke Red and asks him to resign since he is not qualified 
       anymore to be the chairman of the World Federation.


            Back at Doctor O'Shay's house, Inspector Tawashi is
       looking for Astro. Before he even mentions his investigation,
       Astro volunteers to go to the Pacific Ocean to help. Inspector
       Tawashi is highly impressed with Astro's ability.


            This is still a shooting stage. Doctor O'Shay has
       removed Astro's jet limiter so he can fly over the Pacific
       Ocean. Defeat the bad guys with the finger beam and arm
       cannon.


       Stage 2-2 Artificial Sun
       ---------

            The boss and its attack pattern remains the same. Use
       the same strategy you used during the first game to defeat
       the sun.


            In order to avoid repeating information and to save
       space, ALL the enemies you have met during the first play
       retain their attack pattern during your replay games. The
       strategy you used to defeat them should still work.


            After the battle, the artificial sun will try to escape
       towards an island.


       Stage 2-3 Cruciform Island
       ---------

            Upon landing, Astro will meet Pook and the Amazing Three.
       Go kick the arses of the Amazing Three and enter the ruins.
       If you have already met Big X, you can already proceed deep
       in the ruins. Fighting Big X is optional but, hey, it's one way
       of increasing your score.


            Destroy the stone face behind Wally. This will open
       the passage previously blocked. Return to the passage and then
       go down.


       Stage 2-4 Dreadful Robots V3
       ---------

            Beat all the V3 robots to finish the stage. Get the heart
       at the end of the stage to recover life points.


       Stage 2-5 The Elevator
       ---------

            Beat all the giant bees, bats, and mini-V3s  to finish the
       stage. In case you still haven't seen Magma, now is the time to
       do so.


       Stage 2-6 Transformable Robot "Pook"
       ---------

            Defeat Pook in this boss battle. 



  Chapter 3 - Rebirth
  -------------------

       Stage 3-1 Tokugawa Plant on the Moon
       ---------
       Character: Nuka

            Drake is now proclaimed chairman and promises to correct
       the injustice done to humans during Duke Red's term. He plans
       of passing the Robot Regulation Law. All robots that violate
       this will be destroyed. Nuka visits Astro and she asks Astro to
       promise that he'll never forget her. She leaves for Duke Red's
       hideout after the event. Nuka is now officially added to the
       Omega Factor. Power-up any of Astro's abilities to proceed.


            Stage 3-1 is still same. In case you still haven't seen
       Jetter Mars, now is the best time to do so. Anyway, defeat all
       enemies to proceed to the next stage. Get the heart at the end
       of the stage in case you have lost some life points.


       Stage 3-2 Goblin Roboid
       ---------

            Defeat all the goblin-type robots. An interesting glitch
       (thanks to c0rps3) prevents the big Roboid from attacking Astro.
       Before facing the big Roboid, fly over it and reach the right
       side of the screen. Make sure you go OVER and not simply jet
       pass it. To successfully perform this, you need to upgrade
       Astro's jet stat or use the EX Dash. Do not go in front of the
       Roboid or else it will attack.


       Stage 3-3 Power Plant Reactor
       ---------

            Reach the upper portion of the reactor. If you still have
       not seen Fumoon, now is the best time to do so.


       Stage 3-4 Observation Deck
       ---------

            Defeat all enemies to proceed to the next stage. In case
       you have missed Hecate, she is standing on the upper-left part
       of this area. If you have already seen her, a heart will be
       placed in that area.


       Stage 3-5 Astro vs Atlas
       ---------
       Character: Atlas

            The stage starts off with Astro telling Atlas to stop it.
       Crap, Astro even knows Daichi is Atlas. Enough with the long
       talk and the battle starts. Defeat Atlas the same way you did
       during the first play.


            After the battle, the hibernating capsule will fall from
       the ceiling and Atlas will go into his fit again. Astro gets to
       meet Dr. Tenma for the first time. Astro calls him "father" but
       Dr. Tenma is displeased with the way he is acting and leaves.
       Before the stage ends, you will get Atlas for the Omega Factor.
       Power-up any of Astro's abilities.


  Chapter 4 - Rebirth
  -------------------

       Stage 4-1 Antarctic President
       ---------
       Character: Abercrombie

            The Robot Opposition faction has won the election in the
       Antarctic region. Rag, a robot who was also running for the
       presidency, was involved in an "accident". Rag's body was not
       found. Anyway, Astro was invited to attend the inauguration
       ceremony of the new president. The new president turned out
       to be none other than Rock and Drake is supporting him.


            President Rock is obviously not impressed with Astro. And
       all of a sudden, some rampaging robots attack. This sounds
       fishy. It turns out that the robots are not happy on what
       happened to Rag. Help the bad guys...Err, I mean destroy all
       enemy robots to finish the stage. At the end of the stage,
       rescue the human boy from the robots. His name is Abercrombie
       and he will be added to the Omega Factor.


       Stage 4-2 Above the Antarctic Ocean
       ---------

            The stage starts off with Astro following the leader of
       the robots. Anyway, defeat the enemies to proceed to the next
       stage. Use the arm cannon to defeat the giant robot faster.


       Stage 4-3 Follow Carabs!
       ---------

            The leader introduces himself as Blue Knight. He is the
       self-proclaimed avenger of the robots. He plans of building
       "Robotania", a country in the Antarctic just for the robots.
       The Blue Knight believes everything would be different if
       Rag became the president. But Astro tells him that Rag will
       not agree with Blue Knight. Rag believes that it is possible
       for humans and robots to live together. With this statement,
       Blue Knight decided to rethink his plans. Isn't it OBVIOUS
       that Blue Knight is...*gets strangled by his brother*


            Anyway, Blue Knight mentions about the warship called
       Carabs. Defeat the enemies to finish this stage.


       Stage 4-4 Robot Tank Carabs
       ---------

            Defeat the Carabs. After the battle, President Rock
       goes on this robot-hate speech. But Wally interrupts him
       and tells Rock that he is the one responsible for the death
       of Rag. Wally shows everyone a mask as a proof. The mask
       was found inside Rock's house. During the campaign period, a
       man known as Deadcross, with the aid of some robots, was
       harassing the people to give him money. The money was used to
       remodel the Marine Express and smuggle weapons like the Roboid.
       (Yeah, I know. The evidence is weak.)


            With the evidence against him, Rock wears his costume
       and escapes.

       Character: Sapphire

            Defeat Sharaku. After the battle, Sharaku promises Astro

       the time travel took three months to complete. Rock decided

       ---------
       Character: Inspector Tawashi 

            Upon returning to the present, things have gotten so
       different. It seems that three months had already passed since
       Astro and Wally disappeared. YAY! The time difference is
       the same with their stay at the past Mu Empire. During the
       first game, they were five years late.


            A huge robot will introduce himself as Pluto, one of
       BLUE KNIGHT's followers. Blue Knight tells Astro that during
       the past three months, Drake has oppressed the robot population.
       Robots including Zoran, Astro's sister, had taken refuge in the
       Antarctic region. Within 24 hours, the robots will start an
       attack against the humans. Astro mentions the Death Mask and
       this surprised Blue Knight. He accuses Astro as a spy for the
       humans. Anyway, Astro needs to fight the strongest robots in
       the world. You'll fight North first.


            After defeating North, Astro will rescue Inspector
       Tawashi from the cage. He'll tell Astro that Blue Knight got
       the info regarding the Death Mask from Kinsankaku. Inspector

       another power-up.
