Ok i might as well post my impressions too. There will be SPOILERS so dont go on if you dont like them.
I'm loving this game, especially the MP which i think will be incredibley awesome (when we get the Dedicated servers which are a MUST). However i know it's not perfect.
Starting from the SP: I love the fact that the stories interwine but, in my opinion, AvP2 did it way better. I loved how, in that game, you would see the different characters you played from the different POV's. This didnt happen in this game and it was a little bit of a let down for me. The story also didnt really impress me: it just looked exactly like AVP1 movie (+ CM). Of course it had its awesome moments, and overall enjoyable game play. I was just expecting a somewhat more interesting story. Im not even a big fan of Preds being some kind of a Rescue Team (i liked how in AVP2 they went there for the sake of hunting.. if i remember correctly). Killing the queen so early, and figthing Bishop as the last marine boss was just meh...Im not even a fan of the Predalien vs Pred final battle. Also, didnt like how the developers defined him as the Preds nemesis, but we only saw him like once during the campagin?(twice with the cutscene). On the other hand i love all the Praetorian fights, especially the marine one.
I had a feeling that the SP would've been pretty short, and i wasnt wrong. The marine was ok in lenght i guess, the pred could've been a little bit longer. But the alien... wow that was short. Intense, but short. The levels just flew by without me even noticing (and why does it have one level less than the others??). Oh and, please, only 2 harvest animations?
The alien AI kinda surprised me. I think, as a whole, it worked pretty well. They flanked, ambushed, hit-run. On the other hand, the marine AI was pretty silly. And one thing that really annoyed me was how they kept repeating the same 3-4 phrases. That was embarassing... cmon. Overall, i gotta say i enjoyed the AVP2 SP more.
The graphics i think are really nice. Dunno why its getting a lot of criticism. Of course they aren't not top notch, but they're still great. The models i really love. In my opinion, they are very detalied and well made. The lighting is very nice too, so are the sound effects.
With a little more effort and originality, i think the SP could've been awesome. It was not horrible, but i wasnt really that impressed in the end. It just felt a little bit rushed. And yea, i agree crouch in SP would've been pretty useful.
The MP, on the other hand, is extremely fun. I knew it woudl've been, and i wasnt wrong (of course thats just my opinion). The various modes are all pretty awesome (except Deathmatch of course). Suprisingly, i found mix-species DM quite enjoyable. Infestation is just great, so is TDM. Domination is also a nice addition (is it just on one map with aliens vs humans?). Survivor is great fun. I was looking forward to Pred Hunt, but i wasnt really satisfied. The timer just makes people rush and die quickly. You dont really feel like the hunter or hunted (as marine). I probably just need to play it more and get used to it.
I kinda miss the class system (loved Heavy pred), but i can perfectly live without it.
Of course it has its problems (im on PC): The biggest of all is the matchmaking. It looks so much like the MW2 sytem which was an utter fail. Many times the game is unplayable due to the ridiculous pings (im in Italy). And no host migration is just stupid. And also, lobby closing after each match?...But then, on the other hand, we have Dedicated Servers coming soon. Hopefully, they will solve most of the problems and make this game justice (because its has great potential).
Another things is, obviously, the lack of maps. Hopefully we'll get lots of DLC, but imo, they could've given us more maps to start with. Also i agree with the review saying most are jungle maps, which are indeed nice, but not really alien friendly. We need more industrial maps. Aliens are already lacking vents (but i gotta say shadows work very well).
Overall, i think this MP has greater potential than AVP2. Im already liking it more. It feels a lot more skill based (now dont bash me.. i know AVP2 had its moments but most of the time it was just a spamfest)
Oh and, yea, Evac would make this even better
