Legitimately runs like absolute trash while playing co-op with someone on XBOX ONE X. It is in an unplayable state and if you are buying it for the sole purpose of playing with a friend either buy it on PC or be a chump like I am.
Purchased the game two years ago while it was in early access, and to me the framerate issues were acceptable when it's early access, shame i couldn't enjoy the game really but SURELY it would be fixed.
The game has been out of early access for 7 months now and it is still completely unplayable in co-op on Xbox One X due to the framerate dipping so low it becomes a slideshow. Less than a frame a second at times it legitimately just CHUGS.
We don't have a big base so that's not the issue, its like 7 platforms - also it runs PERFECTLY on my friend's PC. But it doesn't run properly for xbox in co-op using crossplay regardless of whether you are host or not, and doesn't work co-op xbox to xbox, both xboxs chug.
Fun game tho, good ideas, hence why I purchased it in early access........ REALLY just wish I could play it.
