To access cheat codes in Project IGI, players typically had to pause the game, press a specific key combination (often Ctrl + ~), and type in the desired code. The codes would then grant various benefits, such as infinite ammo, health, or invincibility. For the full version of the game, several websites and gaming forums compiled lists of working cheat codes. Some popular codes included:
Allows continuous firing without weapon animations.
– Grants absolute invincibility (God Mode) to David Jones.
These codes are case-sensitive and must be typed in lowercase. 2. Unlocking All Missions/Levels
