Homeworld 2 is a real-time strategy video game and a sequel to Homeworld. The story focuses on Hiigara's response to a new enemy, the Vaygr. The game features enhanced graphics and audio, marking a significant step forward from its predecessor. Unlike the closely matched Kushan and Taiidan forces of the original game, the Vaygr and Hiigaran spaceships differ greatly in both design and application.
