Advent Rising

"Advent Rising" is a single-player Science Fiction Shooter game with a marvelous story and beautiful gameplay, accompanied by awesome music, developed by GlyphX Games and written by Orson Scott Card. Despite its cult following and considered an underrated classic, the game suffered from poor critical reception and sells, leading to the cancellation of its sequels. The game was originally conceived as a trilogy, with a PSP title in the works called 'Advent Shadow' that was also canceled.
