Aspyr has released a demo version of Homeworld 2 with 3 tutorial missions and the full, first single player mission of the game. Homeworld 2 is a “sci-fi real-time strategy game where you control vast armadas of ships battling alien forces. You can research and build new technology and control your battle in true 3D with an innovative camera system that lets you zoom in to see intricate details of ships and zoom out to get a system wide overview of the action.”
