I found this.

Oddworld: Abe's Exoddus Invincibility (Playstation)
To make Abe invincible while playing, press and hold R1 and press Circle, Triangle, Square, X, Down, Down, Down, Circle, Triangle, Square, X.This makes Abe invincible against all enemies, though if you fall/jump from a high ledge you will die. Just slap a Slig and see if you did it right. There is no confirmation sound.

ahh thanks crashpunk, i hope it works, it never did before
