Well I'm a huge fan of AvP, so I was looking forward to this game.
However, I was quickly disappointed when I saw the first gameplay videos: graphics looked subpar, the environements looked crappy and the animations weren't convincing.
When the demo came out, I downloaded right away (even before BC2), hoping for the best..
I tried the game and was really disappointed.. it's a crappy game: terrible graphics, crappy commands etc etc..
I won't buy it, that's for sure.
I can only see myself buying this when I find it in the bargain bin for 10 bucks or so - and even then, only if there's nothing else worth playing around - but just because it's AVP.
To be honest, I think this is one of those games you buy a have fun with for a coupel days, then sell it and forget about it before the week is over..
Rent it if you must, don't buy it.
