Undertow: Path of the Elect

The Undertow: Path of the Elect expansion pack extends the full game by featuring a full, five level single player and co-op campaign and introduces an entirely new playable race known as the "Elect." Armed with superior technology and fire power, this fanatical alien race is determined to rule the earth and destroy those who seek to stop them. Multiplayer fans can now choose to play as the Elect or as one of three other races as they explore four new multiplayer maps and earn points for upgrades by killing enemies, completing objectives, and taking checkpoints.
