Project Delta is a futuristic first-person shooter spanning three time periods as players attempt to destroy two aggressive alien races from their home planets. Both the Cryzen and Dorians are locked in an epic struggle for world domination, and players must eventually journey to each race's home base to destroy them from the inside out. As in similar games like Halo, players will periodically fight alongside computer-controlled soldiers to accomplish various objectives. These troops will gain experience over time and become close allies in the battle to save Earth from a dark fate. In addition to the main single-player campaign, Project Delta includes online multiplayer action via Xbox Live. ~ Scott Alan Marriott, All Game Guide
