http://tvgry.pl/?ID=805They played sp only( the whole sp campaign, 3 species i think but not sure). They said that overall AvP is good game but the were expecting something more form it. From the 3 species they liked alien the most with it's stealth gameplay, marine was the worst - not scary at all, straight for A to B shooter, pred was in the middle. There were very few cutscenes and the story didn't draw them in.
