I got to play it for a little bit just now (30 minutes), and I can say that i'm pleased. It seems like it would be lots of fun with co-op, but I played it solo.
It's very much like Sniper Elite v2 with the same basics, but this time zombies are popping up out of the ground and such. It gets tough when at sections when they all come at once, some even running with grenades and explosives.
Pretty good so far
Only gripe is that crossfire didn't seem to work...
Edit:
TheHunter said it better and with illustrations
