Hints & Tips

Beating the computer
It is easier to beat the computer if you run counter-clockwise around the room. Run in a circle since Konoko can move qucker than the laser beams.

Beating Barbras
Simply knock his gun out of his hands, then pick it up and shoot missiles at him. If you are out of ammunition, let him pick it up and when he charges it up, get it from him once again. Note: This will not kill him the second time that you have to fight him.

Beating Shinatama
When your in the Dream Diver level, enable the "Last Man Standing" cheat and rush to the part where you have to fight the Cloaked Ninjas. If you are fast enough, you will see Shinatama "trying" to fight the Ninjas and you can kill her. Note: You will not lose the level if you do this.

Multiple endings
After you beat the computer you are faced with a choice either kill Commander Griffin or not. Your choice will effect the ending Boss fight. Should you choose to shoot him, you will make things harder. At the last battle you will face your brother after he transforms into a monster. If you do not kill him, the final battle will be easier. This time, your brother will come near you with two of his troops and will not transform. Do not worry about the troops, your old "friends" from the TCTF will help you, as well as Commander Griffin, leaving you to face your brother. With either choice, the ending sequence stays the same.

Beating the Boss after the brain computer
The Boss after the brain computer has the Wave Motion Cannon. When you start, run at him at an angle and jump kick the gun out of his hands he will fall down. When he is on the ground, run over to the gate with the two fallen guards on either side. Go to the right and pick up the Hypo. Now use it, and when you are super charged go for the Boss. This should make fast work of his health. If he has any health left use combos on him.

It is easier to beat the computer if you run counter-clockwise around the room. Run in a circle since Konoko can move faster than the laser beams.

Beating the second Deadly Brain
When your on Level 13, hold onto a mercury bow that you obtain in the stage. Be sure to have some ammunition. When you are fighting Shinitama, go up to Griffan's force field. If he is not standing by the force field, hit one of the switches and go back. After he is near the force field, shoot him. If done right, he will get hit and come through the force field at you. Then hit him a few times to win. Note: You cannot get the "Didn't kill Griffan" last Boss battle if you use this trick.

An Innocent Life: Easy robot target
When your on level 8, "An Innocent Life", one save point is in a room with three or four robots, deadly green ooze below, and sparking arcs of electricity that you have to avoid to reach the other side. From the save point, run up the stairs and watch for the robot up there. Then, hop down at the outcropping to the Terminal below. You should have avoided the first half of the first arc of electricity. After you drop down, the robot guarding the terminal to shut down the arcs of electricity will not usually "see" you, since you got there the wrong way. He will now be an easy kill.

Rooftops: Beating the ninja
Use this trick to easily beat the ninja at the end of the level. Obtain and keep the Screaming Cannon. While your fighting the ninja, stand with your back to the elevator door that you came out of. The ninja will teleport and get stuck in the elevator behind you. Walk forward, turn around, and you will be able to see him attempt to run through the door. Now shoot him with the Screaming Cannon and he will die. Note: At times he will teleport beside you. If this occurs hit him until he has to teleport and try standing in front of the door once again.

Syndicate Warehouse: Unlimited time
When your on the truck section, you will have three minutes to reach the console. To have no time, first reach the floor of the console. There will be a striker. Turn the console but do not kill the striker. It will have no time after this. Note: If you leave the area by the console and go back, you will trigger the intermission sequence and win the level. Also, to keep the striker from killing you, get rid of his gun then run.

Atmospheric Conversion Center (interior): Easier start
When you start level 14, attack the enemy which is in front of the pillar that you started out at. He will attack you also. When he does, run behind the pillar. This will "bring" his other patrolling friends at you. This will be easier than running into the open, where a sniper is waiting. When all three of the enemies appear, duck and kepp tripping them. This works if you disarm the man carrying the gun. When you have beaten them, look to the left of where you started at. There will be an invisibility item. Now pick it up and run towards the exit where two guards are at. If you try to kill them, you will most likely get shot down by the sniper.

Bio Lab: Force Shield
When your on the Bio Lab level, right after you beat the Boss, go to the door to the second save point. After you save the game and you have made it up to the second floor, save the scientist in the back of the left-side room. After you do he will give you a Force Shield which will stop every bullet that is shot at you. Note: Even with the shield active, hand to hand combat still can harm you.

Dr. Hasagawa's Lab: Big Head mode
Just start level 12, "Dr. Hasagawa's Lab". Get to the part where four tiny strikers rush you. Now kill all of them before they escape back into the wall to access the ''Big Head'' cheat.

Gun special attack
Simply equip yourself with a two-handed gun like the Plasma Rifle and keep it out. While your  rising from a crouch press [Shift], then release then press [Kick] and Konoko will preform a Jump 360 attack. Note: You can fire while your doing this, just aim carefully. Also, this will not work with the Wave Motion Cannon because by pressing [Kick] with this gun will launch grenades.

Mukade's tracking fireball
First enable the munitionfrenzy code. Now on the left and right of the Wave Motion Cannon, there will be one dot on each side. One has a WMC logo that does not work and the other has a Mercury Bow logo. Grab the Mercury Bow dot. Fire, and it will be the same weapon that Mukade will use. Note: This is like the Screaming Cannon; it will hit you if there are no other targets around.

Truth And Consequences: Walk outside
When your on level 9, "Truth And Consequences" you will start in a room with a man you can talk to. He will tell you he has a wife and kids. Exit this room and go into the front atrium. In here you will see the locked front door, two staircases, and plenty of glass. Shoot out a square pane of glass, then run and hop through. You will be outside on the streets. The programmers expected this and placed roadblocks here at the end of each street. You cannot run around too far. Note: At every roadblock are two enemies, with at least one carrying a Mercury Bow. If you are quick enough you can see them pop into place. If you are careful and fast enough, you can grab a Mercury Bow from one of the opponents and it will still have one shot left. When you wish to go back into the building, run up to the front door and it will open, and lock after you. If you do not kill any of the opponents that see when your outside, they may come stalking after you in the building. Going outside and then reentering the building at times causes a problem in the game where it will stutter every second or two.

Sliding
When your facing a tough enemy in the later on levels, aim high up with a weapon in hand dash to an opponent, slide star to dash then press [Shift], but do not knock the opponent down. While you are sliding, start to shoot. This is an easier way to win because it is hard for the enemy to aim at you.
