Destroyer and I have been playing this. Free with Game Pass. Very similar to Left for Dead. 4 player coop mode. If there is any interest I will put up an event to run it one night.
I got thus when it came out, loaded it up, didn’t play it, and have yet to try it.
Some pretty easy achievements on easy mode. To run it higher than easy mode you need at least one more player. A four player team would be ideal. It is not as complex as the COD Zombie maps. We have been going back to those recently and they can be brutal.
