Does using walkthrough regard as using cheats? I guess it does. Well, I use walkthrough whenever I really stuck in the middle of a game without knowing what to do & where to go next. But I will try my very best NOT to use any cheats cause without cheats means more fun to play.
Other than that, I remember I used cheat with unlimited ammo,health or god mode in certain levels of FAR CRY cause some levels are tough to stay alive....
