"Homeworld 2 is a real-time strategy computer game sequel to Homeworld, developed by Relic Entertainment and released in 2003 by now defunct publisher Sierra Entertainment. It takes place after the events in Homeworld and concerns Hiigara's response to a new enemy called the Vaygr. It features enhanced graphics and audio and its gameplay takes a new direction. Vaygr and Hiigaran ships differ significantly in design and application, in contrast to the closely equivalent Kushan and Taiidan forces of the original game.
