The Invasion of Area 51

In an alternate tale of the Area 51 raid, you play as the last man standing against a seemingly endless horde of crazed-civilians. You have an assault rifle, top-secret government weapons (like a black-hole grenade), and a helicopter to bring you supplies to stay alive. Gather points from enemy eliminations to purchase upgrades and abilities to strengthen your defense against the fearless horde. Support for both first-person and third-person play styles.
