WP writes: "Halo Wars is a strategy game based on the legendary Halo universe. Players will command armies of familiar and new UNSC units in its initial encounters against the Covenant, an alien coalition threatening to obliterate mankind. Halo Wars will immerse gamers in an early period of the storied "Halo" universe, allowing them to experience events leading up to the first Halo title for Xbox.
With the guidance of Serina, a spirited artificial intelligence (AI) persona, gamers will direct legions of UNSC soldiers, Warthogs and Scorpions against Covenant Grunts, Elites, Ghosts and Scarabs, each group having its own strengths and uses in battle. Strategic-minded players who react well under pressure will emerge victorious."
