Grand Theft Auto: Vice City/Cheats

PC
Just type code in while playing. Alternately, open the menu (Esc) and type them in there. The advantage of typing them at the menu is that you can receive their effects right away (rather than having a delay while you type it in) and the keys won't result in actions you might not want.

Xbox
All cheat codes must be entered while playing.

PS2
Enter these codes during gameplay without pausing.
