ABOUT THE GAME
Sanctum - first-person shooter developed by independent developer Coffee Stain Studios.
Sanctum 2 - continuation of an interesting hybrid game combines first-person shooter and strategy (Tower Defence). The new part of the game we will have a large number of new maps, updated tower, new monsters, plus now we will have a choice between 4 new classes of defenders, which can be pumped and open a new, more powerful weapons. Each class in the game has both strengths and weaknesses, so that the survival of normal maps take several allies alive.

The very same gameplay is not particularly changed, we still need to build the most difficult routes for monsters to fill these routes are the deadly turrets and not to allow the enemy to the core, which produces oxygen in this strange world. And to help in this difficult battle, you can invite three of your friends, and then the four of us to defend the planet from destruction of the cores (nuclei) that produce oxygen.
Story campaign can go in alone, but better with a partner, it´s a cooperative game.
