Definition: Hidden items within games are referred to as Easter Eggs. Most Easter Eggs that are found are put there specifically by the developer, sometimes for humor, and sometimes because they may have forgotten to remove a code they were playing with while developing the game.
Also Known As: Hidden Items
Examples:
An Easter Egg can be found on level five above the entrance to the room, simply turn night vision on and you will see the image of a soldier having a drink.
