Seems like this thread died before the game even came out.
I bought this game a week ago and had a blast playing it, eventually i got the platinum trophy for it. The game is pretty easy, even on hard. I did get stuck on the zombie baseball game in stage 2. Had to replay that at least 10 times to beat it when i first got to it. But once I learned how to beat it I was able to pass it without dying, which was needed to beat that stage in the ranking mode. The camera can be a little annoying at times but nothing major.
Overall i think the game was pretty cool. But levels felt too long IMO. Most of them take 30-40 minutes to beat. I think it would have been better if they at least had checkpoints you could start the game at, instead of having to start at the very beginning of each stage. I also didnt like how you couldnt buy things like outfits, records, photos in the menus. You could only access the store by going through a stage and finding one which takes 5-10 minutes.
Zed was probably my favorite boss character in the game. I liked how they gave you a lot of clothing options to unlock in the game, instead of making most of them DLC like some games do these days. So yeah it was a pretty fun game, and its only 20 bucks now, so if you never got this game i would recommend it.
