Coffee Stain Studios did a great job of improving on their formula from the first game. A lot of people don’t know (myself included) that during the same time Sanctum 2 was released, Coffee Stain Studios released another game in the Sanctum universe. It was a pure tower defense game called Super Sanctum TD. Well, now that I have played it, I can’t believe I missed this gem of a game.
