Aliens: Dark Descent. It's way better than I expected, not just in the gameplay but nailing the vibe of the movie. Fireteam Elite was a fun wave shooter but it turned the xenomorphs into cannon fodder for an action shoot-em-up. Dark Descent is survival horror. Fighting is a last resort. You spend your time creeping down dark corridors hoping you don't see a xeno, because when you do the hive wakes up and bad things happen. Like in Alien Isolation, your best bet is to watch your tracker and be where the xenomorphs aren't. Your marines can get wounded, killed, or dragged off to be an incubator. They also suffer stress, and start to freak out the longer they are in danger.
Really enjoying it so far!
