Xeno Tactic is a game that offers a new way of playing a classic game of defense. You are the one in charge of the position of the turrets that you place on a grid, which in turn leads to you being able to create your own paths for the Xenos to follow. This is possible by building different types of turrets, each of them has its own abilities and its own special place in the map.
The game has an extensive and complex map that will challenge your strategic abilities. Each level is different and will require a different strategy.
