Sanctum 2 is the sequel to a popular hybrid game that combines elements of FPS and tower defense fairly solid. During the game will switch between placing towers which eliminate enemies and thanks to the variety of enemies makes the game quite chaotic, we also have to attack in real time as an FPS it comes up. While we can plan a little, we are forced to make quick decisions during the game and that's what makes it so frantic.
Each level begins with the placement of the towers, which helps prevent the enemy breaks with the core we are defending. In each level and wave, will have a certain amount of towers to place. As they put towers will also create a sort of maze that will prolong the journey from enemies to the core, while the towers inflict damage on monsters that shoot lightning delay, among others. Each is effective against a different kind of enemy, so they should really be careful about choosing the towers.
