I've only had a chance to play the intro and part way into mission one so far.
That play session came to an end when one of my squad members passed out during an intense battle so I grabbed him up and made a retreat. It was actually an incredible experience and felt authentic Aliens. Laying down fire while being on the back foot, it was the hive scene from the second movie.
I'm not usually a big fan of these types of games but it's won me over. Can't wait to dive back in.
