Unlockable games

From Wikipedia, the free encyclopedia

The term unlockable games refers to full video games that can be unlocked within another videogame, often as easter eggs. Often these unlockable games are earlier entries of the series of the game in which they are hidden, such as NES Ninja Gaiden series in the Xbox version of Ninja Gaiden, which become available after beating the game with certain requirements.
