SEGA has confirmed that Universe at War: Earth Assault for the Xbox 360 has shipped to store shelves across North America. The combat-intensive real-time strategy game thrusts players into an epic struggle to prevent total annihilation of life on planet Earth. Universe at War: Earth Assault supports Microsoft’s Games for Windows LIVE initiative and allows cross-platform play between Windows-based PC and Xbox 360.

Universe at War: Earth Assault is set in the near-future, when Earth has become a battleground for three different alien factions: the ravenous Hierarchy; the futuristic Novus; and the mysterious Masari. Universe at War: Earth Assault also employs a unique balance system called "Tactical Dynamics." This groundbreaking feature allows players to retrain and customize units in the midst of battle to better cope with enemy forces and challenging tactical situations.

Weaponry and defenses can even be modified in real-time, allowing players to take advantage of constantly shifting battlefield conditions. Fully customizable tech trees allow players to control the development of technologies that they deem key to victory. With deadly super-weapons and alien powers, players can destroy large-scale cities and whole territories in one devastating move.
