Alrighty! Sanctum 2 was, when I started playing it, one of the neatest genre combining games I had played in awhile. As an FPS/TD hybrid, Sanctum 2 managed to really help me feel the tension that normal tower defense games really didn't deliver. It can be a little clunky at times but the fairly open ended maps really allow you to experiment with wall and turret placement, as well as where to place your character for maximum effectiveness. It teaches great game sense, if you can get the hang of it, as it promotes a wider awareness of what is going on around you. Thanks for participating, best of luck!
