In this game, you can set up towers strategically to defend the base (all instructions are explaned in game). Enemies can come from varying directions so the towers make decisions who to shoot, but if they don't get the job done, you can take control of the towers directly turning the gameplay into somewhat of a shooter. Towers are upgradable, but so are the enemies which begin to get harder as the game goes. The game also features dynamic difficulty adjustment by changing the number of enemies that come each wave based on how hard it is for you to handle it.
