Undead Labs has posted a small article about reviews they are receiving from various sources. It's sounding really good for this game so far. Too good to be true? I don't know. Previews are nice and all. but I just can't give them much credit until I'm playing the game myself. What they are saying sounds awesome indeed though. I'm trying not to be excited for this game, but it's hard.
Separate links for the previews.
