Sanctum 2 is the sequel to its incredibly popular PC title, Sanctum. Since launching on Steam in April 2011, the tower-defense/first-person-shooter genre bending Sanctum has sold over 300,000 units.

Sanctum is a fresh take on the tower defense genre and places the player right into the frenetic fray with tight first-person shooter gameplay mechanics. Gamers take the role of Skye, an elite soldier sent out to protect her home town, Elysion One, from hordes of mysterious alien creatures. To successfully defend your land, you must construct and upgrade a labyrinth of defensive structures and towers. When the havoc starts and the wave of baddies is unleashed, you jump right into the action with your own fully-upgradeable weapons and play a key role in the defense. Sanctum has taken the best features from FPSs and tower defense games to create something totally unique, and Sanctum 2 will only build on and improve that experience.
