Halo Wars is an Xbox 360 strategy game developed by Ensemble Studios (to be shut down by publisher Microsoft), based on the legendary Halo universe. In campaign mode, players will command the armies of the UNSC warship "Spirit of Fire", consisting of familiar and new UNSC units in its initial encounters against the Covenant, an alien coalition threatening to obliterate mankind. With the guidance of Serina, a spirited artificial intelligence (AI) persona, gamers will direct legions of UNSC soldiers, Warthogs, Scorpions and more. Adventurous commanders can also call upon ancient Forerunner technology, if they are fortunate enough to find it hidden throughout the battlefield.
