Dunno if it’s MP compatible yet, but the newly released Day One mod attempts to simulate the first day of the Knox Event. Tons of NPCs (using a new engine instead of the built in AI), bombs dropping, different factions, etc. Crazy experience thus far, and you’ll probably die faster if you’re not careful.

Still can’t wait for build 42 tho.

I’d be curious to see if you can install the patch that reintroduces the E3 graphics and how that’s handled on the Deck. Not sure on the how-to with SteamOS.
