Geist (stylized as geist) is a first-person action-adventure video game for the Nintendo GameCube, released on August 15, 2005, in North America; on October 7, 2005, in Europe; and on November 3, 2005; in Australia.
A prototype of the game was developed by n-Space, who approached Nintendo to be the game's publisher. Nintendo accepted, making Geist the second GameCube game published by Nintendo to receive an M-rating (the first being Eternal Darkness: Sanity's Requiem). In the following years, Nintendo and n-Space worked closely on Geist. The game was first shown at the E3 2003 and was announced to be part of the GameCube's line-up for 2003. However, it was delayed multiple times, making it two years of delay for fine-tuning. During that time, the game's genre changed from first-person shooter to first-person action-adventure with second-person elements. The Geist franchise is owned by Nintendo, due to their contract with n-Space.
