I never used cheatcodes for completing a game but today I installed Cheatbook 2006 provided with Digit DVD, & so I decided to try cheatcodes first time. I searched for Project-IGI (I M Going In) & found cheatcodes like Type NADA at main menu. I m unable to understand that where shud I type that. Other games also have cheatcodes like type at........ but no such place found to apply a cheatcode. Can anyone tell me that how to do?
