15 Best Alien-Focused Single Player Games You Need to Play

Halo: Reach

A prequel to the original Halo trilogy, Halo: Reach pits you as Noble Six – member of an elite squad of Master Chief-alike super-soldiers – against the intergalactic conglomerate of alien zealots the Covenant in a staunch defence of the human world Reach. Perhaps owing to its depiction of events shortly before Halo: Combat Evolved, Halo: Reach harbours gameplay like Halo’s first albeit with updated versions of old weapons alongside new firearms. The Covenant are present and correct though, a spectrum of alien enemies including the industrious Elites and cowardly Grunts.
