From reading an early play though there are holes in the walls, floors and ceilings the Xenos can appear through so it’s not always like a horde style they’re all in front of you to be mown down type of game.It looks very average to me, I believe it's launching at a lower price point so it might be worth it on those grounds, seems like they have tried to be faithful to the franchise and there's a few nice details (Artificial people as the bots).
I just don't get a sense of any atmosphere or dread seeing as you are mowing down waves of Xenos effortlessly. I hope it's decent though, could still be fun with friends.
