Cheat codes may sometimes produce unusual or interesting effects which don't necessarily make the game easier to play. For example, one cheat in "" makes dinosaurs appear "undead". Another example occurs in the game "Dungeon Siege", where activating the cheat to extend the range of a bow also allows the enemies to fire at the same distance, thereby eliminating the advantage the cheat would have given. A cheat may even make the game harder to play; for instance, one could give the enemy special abilities, increase general difficulty, make neutral bystanders attack the player or grant the player a disadvantage such as low health points. Cheats in "Grand Theft Auto" games can make NPCs start rioting or wield weapons. In "Grand Theft Auto III", the player can activate a cheat to enable blowing off the limbs of NPCs, a feature originally included in the game. 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.
