ZeroTolerance Writes: The puzzle genre has not seen innovation in some time. Sure, Puzzle Quest upped the ante a bit, but something so far out there that makes you step back and re-think your strategy has been in remission. In comes Slam Bolt Scrappers, a wildly twisted take on the genre. Think one part tower defense, one part Tetris and even one part Smash Bros. and you’ll begin to understand the core concept. This is one twisted game, but, once you get the hang of the controls, it also becomes one of the most addictive couch co-op games available on PSN.
