I suggest that patient gamers put Aliens: Dark Descent onto their wishlist and wait for a good sale. It already had a small sale but the game only came out in June.

They really nailed the vibe, just all around, check out some Youtube plays of it to see if you like the gameplay. It looks like XCOM in screenshots but plays in real-time. The story takes place in a Weiland-Yutani mining base, of course isolated in an unwanted corner of the universe. A mysterious infection has appeared on the planet! I wonder what it could be? Better send some soldiers from your crashed ship to check out the situation and look for survivors. The characters are all new.

I'd say that the game benefits from all the comics and other less-known canon that fleshes out the world, and has the flavor down pat. They haven't forgotten that the original movie was about a conflict between two powerful women, one of whom really doesn't want to fuckin be here, and the gameplay does a great job of being a balancing act between making you fuckin sweat at the mercy of xenomorphs while also feeling like a badass. It's a lot of people's Game of the Year already, so I'd look into it, even though it's gotten kinda lost in the shuffle.
