Now, the framerate, It's garbage, and potentially unplayable past a certain point. I'm talking a consistent, rock solid, sub 10 FPS the majority of the time. It gets progressively worse, but the bad starts on stage 5 at least. By the time we got to 8 or 9, it basically always sub 10 FPS. I don't understand how this game can run so badly. If you play solo, the framerate is not as bad, which makes sense, but it still goes down the toilet. I couldn't imagine what 4 player co-op is like, since there were 3 of us and it was a nightmare. I haven't experienced a framerate this consistently bad since PS3 Skyrim, and this is much worse.
I wouldn't recommend this game to anyone, which is a shame because I actually really like playing it. It's a really fun game, especially in co-op, but it feels like there was absolutely no QA done with this game. It's insultingly bad, and it should be pulled from the store until it's fixed.
