 Recently, however, Rockstar Games has not included such violent or unusual cheat codes in its games, instead choosing to focus on cheats such as vehicle spawns, player effects (for example, invincibility) and weapon spawns.Some games humorously penalize the player for using another game's cheat codes.For example, using cheat codes from "Doom" in "Descent" only displays sarcastic messages from the programmers on screen; using codes from "Descent" in its sequel "Descent II" lowers the player's shields and energy to 1%.
