In level 1-4 (i forgot exactly)
In the first level where you get the party power
kill all monsters in the area, and then run back to the cave you just passed by.
This is found by moving to the bottom right of
the location of the party cheat.
Once you entered the cave, the party power will still be active, and wont run out.
Player 1 will have all powerups, and player 2 will
have all powerups exept speed, Which should
be easy to buy since you got everything else now.
Note: This cheat might not work on all versions of Chaos Engine, as the bug might have been removed by Bitmap brothers in a later release.
