Excerpt: "Sanctum 2′s organic intro seamlessly begins the story blends the building and active into one, all from first-person. Britech is being attacked in waves, and you’ll see things on fire and scientists scrambling. It’s neat to see rather than this disconnected areas. You get a mini-map in the upper left-hand corner showing you the arena and the flow of the monsters. And you’ll be able to setup barriers or barriers with guns to alter the path and lengthen their travel time to the core. Pretty standard fare for tower defense. The varying difficulty in the enemies that spill out of the monster faucet keep you on your toes and allow you to vary your strategy."
