Sanctum has just been updated with the "Elysion One Overrun!" patch which includes:
1 new map (Complex)
1 new weapon (Shotgun)
2 new towers (Holo Tower, AMP Field)
Customization System (Equip towers & weapons of choice)
Loads of fixes and changes!
Sanctum is a First Person Shooter Tower Defense where you take the role as Skye, an elite soldier sent out to protect her home town, Elysion One, from hordes of mysterious alien creatures.
To succeed you have to construct and upgrade defensive structures. What makes Sanctum unique from other Tower Defense games is that when the havoc starts, you jump right into the action with your own weapons and play a key role in the defense. Sanctum has taken the best features from First Person Shooters and Tower Defense games to create something totally unique.
Key Features:
Experience a brand new mix of genres!
Team up with a friend in co-op mode!
Develop your own strategy and build your custom mazes
Play through beautiful environments with unique strategic possibilities
Powered by Unreal Technology, Sanctum is one of the world's best looking independent developed games!
