Easter egg

An easter egg is a hidden surprise or trick that is like a cheat code, but without the code. They are small surprises programmers add to the game for players to uncover, much like candy eggs in a real-life Easter egg hunt. Many easter eggs are purely for entertainment. Some examples include hidden names or faces of programmers, references to other games, or messages for the player.

Easter eggs should not be confused with glitches, cheats, or techniques. Many do not alter gameplay at all.

Examples

Barrel (trophy) - On one the bottom of the Barrel trophy is the message "2L84U". When spoken, it sounds like "too late for you", referring to the usual KO after being shot from a barrel.
