In the original Homeworld, descendants of Hiigara fought their way to their ancestral home. In this sequel, a renegade clan called the Vaygrs threatens the Hiigarans' existence. Gamers must collect resources, construct space fleets, and battle the Vaygrs to survive. Despite some slowness in cut scenes and between missions, Homeworld 2 combines intense action, an immersive story, and detailed 3D graphics to create an enjoyable space-strategy game.The demo version provides one tutorial, two single-player missions, and two multiplayer missions, as well as a single-player deathmatch against the computer. The tutorial provides a cursory introduction to controlling the camera and the basic interface, but you'll need more practice to master all the controls.
