Game Description:An alien race has invaded Earth, and the final outcome is your choice â€“ will you help the aliens conquer our planet, or aid the humans in a desperate fight for survival? Break the mold in an all-new sci-fi strategy game which allows you to change your tech tree, swap out weaponry, and even re-train units while they're engaged to thwart your enemy and turn the tide of battle. Large, beautiful environments remain persistent, so that city you leveled will remain a smoking ruin, but be aware you're fighting close to home. Battles will take place on Earth with familiar landmarks. Special hero units will lead your forces into battle and introduce a fast-paced tactical battle system.
