Infinite power up from start of game: When you first begin the game and are in the room where you first get a weapon and learn how to turn items into Elixir, turn both weapons that you get into Elixir. Because the programmers did not want you to have to start without a weapon, both weapons will re-appear. Collect both weapons again, then turn both of them into Elixir again. Repeat the process as long as desired. Because Elixirs are used to power-up you can make your character as powerful as desired immediately at the start of the game.
Alternate ending sequence: Successfully complete the game two times to view an ending sequence that features a bonus FMV sequence.
Do not lose items when you die: When you die, press Home and quit the game. Reload the same file and you will have the items. However, you will be as far back as you were when you saved. Be careful when you do this.
More elixer: When you first start, go to the red glowing circle and press X. It will teleport you to a room with two weapons spinning on the floor. Pick these up and press X to open the customizer. Once inside, go down to "Equip". Press X(2) and you should see one of the weapons become highlighted. Press Triangle on the weapon and select "Return to elixer". This gives you more elixir to customize your body. Exit this screen and the weapons will reappear on the floor beside you. You can repeat this as many times as desired.
Get the weapons in the start and turn them into elixir until you upgrade yourself very high. Then, clear the first and second floors. On the third floor, get a 75mm Howitzer, at least one Gattling Cannon, and the ammo pack legs. Go back to the first floor and start overkilling by shooting with the Howitzer and holding the Gattling Cannon to finish. Each opponent should drop three or four weapons at a time, and you will find at least one opponent per room, if not more. Continue doing this and selling the equips you find You will get around 5000 elixer each time you clear the floor.
