In 2008 it was announced an Ender's Game video game was in the works. It was to be known as "Ender's Game: Battle Room" and was a planned digitally distributed video game for all viable downloadable platforms. It was under development by Chair Entertainment, which also developed the Xbox Live Arcade games "Undertow" and "Shadow Complex". Chair had sold the licensing of "Empire" to Card, which became a bestselling novel. Little was revealed about the game, save its setting in the Ender universe and that it would have focused on the Battle Room.
