On PC, GTA III cheats are typed on the keyboard during play, letter by letter, with no need to pause. You can type them at any time, even in the middle of a mission. A message confirms that the cheat has been activated. There is no separate box to type into: the game reads what you type while you drive or walk.
Cheats and saving
Unlike later games, GTA III does not block achievements or mark your save when you cheat. The only lasting effects are the two pedestrian cheats, which cannot be switched off once used, and the grip cheat, which stops Unique Stunt Jumps from counting while it is active. If you are going for 100%, save in a separate slot before trying the pedestrian cheats.

Console versions
The PlayStation 2 and Xbox versions use button sequences instead of typed words, entered during play. The effects are the same as above. Mobile versions accept the PC words through an on-screen keyboard.
