It was fun, short yeah. I see the 800 points because it has online co-op. Makes me more interested for the next Dead Rising.
I like the PA announcements, about dinner, and the signs in the cafeteria. Pretty much like they are feeding whoever eats it, zombie flesh. I take it as that at least.. as trying to test on their own workers, seems like something the company would do.
Final boss took me a few tries, than I got the hang of it, wasn't so bad after that. The credits were pretty funny, I'm glad no zombie jumped up making me shit my pants again.
