Awful game. Not even worth £3.74 IMO.
I bought this for £3.74 in the sale for both me and my mate so we could play co-op. We finally got round to playing it this weekend.
I fully expected it to be awful after the bashing it's received on here (well everywhere

We got about half way through the campaign. I think we did 5 or 6 missions in co-op. Not to mention some Alien vs. Marine one on one deathmatch

I was pleasantly surprised, it's actually quite fun if i'm honest. It's not as atmospheric as the Original AvP (what a game that was) but it does get tense in places. We did jump at a few points! You also have to be mindful of ammo as you can run out if you're trigger happy. I also liked the nods to the movies.
I have a few small gripes with the game.
The alien controls for the deathmatch aren't fluid. Changing between walls and objects is a bit clumsy. You definitely have an advantage as the marine.
The menu system to start a co-op game is too complicated. Once you have worked it out it's ok but they could have improved this.
Now for my main gripe. I'll spoiler it as it is about a specific level.
I think it's level four or five where you're captured by an alien. You have to sneak out of the hive without making a sound. The animation for the aliens that are walking around is appalling. I don't know how they ever left it like that! They look like miniature T-Rex's that need the toilet 



I'm quite frankly surprised it got so badly panned. Perhaps they have heavily patched it since release and i've been lucky to come to the party late?
I wouldn't want to have paid full price but for £4 it's a decent co-op game.
