I was pretty excited for the survival mode in this game since the rogue-lite aspect brought over in the SoR4 equivalent tripled my hours in that game. Sadly, the power ups are mostly temporary making it a bit less exciting in Shredder's Revenge. I still think it's a lot of fun though. I also wasn't expecting there to be a (small) bit of a story to it. The different visual styles were neat too. Oh, and it goes without saying, but the 2 new characters are a welcomed addition.
