Excellent game. Not as scary as the first one (maybe just because we know the grisly necros by now..) but mechanics are smoother and feel more polished - especially the new stasis recharge and telekinesis. I liked this one much, much better than DS3.
Same as in DS1, survival horror veterans (RE1-4, silent hill..) might find normal too easy after getting the hang of the first few stages. In both DS1 & 2 I had incredible stockpiles of ammo and healthpacks and 3 guns fully upgraded. So maybe start DS2 on "Survivalist" (hard) if you played DS1!
Great games !!! Enjoy !
