Cheat codes

From Duke Nukem Wiki

Cheat codes give the player an advantage during the game, from invincibility to infinite ammo. Originally, cheat codes were programmed into a game so that the developers could test the game easily without having to play it properly (i.e. they could become invincible so that they could fully explore what they had created). Since then, cheat codes have become a fond favourite of many people and developers.

Sometimes game developers will insert cheat codes that actually hinder the player, or restrict them in some other way, such as providing all weapons but when the player next dies the game quits. Some cheat codes exist purely for amusement, and serve no real purpose in games. Such cheat codes may also be called Easter eggs.
