When playing, press the letter "O" button for the option window, then press the following "case-sensitive" codes:

MONEY = 1000 to your treasury
NOHIT = Team Is Invincible
HEAL = Heals Injured Team
AMMO = Gives Ammo
EXP = Gets 2000 Experience

You will hear a sound when ever the cheat is entered to confirm usability

Have Fun!!!
