Do you like to play bad games as a guilty pleasure? Go for it. Is the game dirt cheap? Sure. Do you like Alien? Well, at this point you might as well play it. But seriously, only play this if you answer yes to these questions. Otherwise, there are way better games out there. I just happen to play bad games as a guilty pleasure. Please take this into account, as this is a very conditioned recommended review.
Ok, if you want a really really good Alien game, go play Isolation, plain and simple. Now, Aliens Colonial Marines suffered one of the firsts popular downgrades during E3 2012, and people are too hung up on that demo and think "Oh the game we could've gotten." And I'll be honest, that game was maybe there graphically speaking, because all the stuff behind that shiny demo, I guarantee you, it was still going to be the same thing and everything would've turned out the same.
With that being said. Aliens CM is an interesting game, it has some cool references to the source material, there's some love there but it never quite gets there on what it tries to achieve. Some vistas look very good, and some areas have a good atmosphere. You will visit some familiar places like LV-426, features familiar cameos, and there are some good moments through out the campaign, but don't think your're going to get an amazing story telling experience. It's a cheesy, and predictable campaign. I liked it.
Gunplay, oof, this is one is a hard miss. Some weapons feel good, like the shotguns are amazing to pulverize Xenos, but others like the Pulse Rifle feels very off, and it always feels like you're not hitting anyone. Don't know, it always feels weird to shoot. Xeno fights = fun, Humans = not so much because of this, and feels unbalanced.
Regarding the AI, PLEASE search how to fix this, as it's a very simple typo fix to do that improves the game, because it fixes the AI, but don't think it's an amazing AI because of this. It will still cheat, and you will see the enemies, specially Xenos, pass through and ignore your teammates to get to you. Didn't like that.
At this point getting the Collection is basically super cheap, which has the positive of getting the Interrupted Stasis DLC, which is a fun small campaign featuring a familiar character. It's a tie in between Aliens and Alien 3.
I can't comment on MP, or the other modes, because they are basically dead unless you play with friends.
And always remember: Gearbox fckd up this game, as they blatantly shifted resources to Borderlands 2 and just wanted this game out of the way, did wrong on the franchise and the player base.
