I've been having some fun with this one. The bots are decent and remind me of black ops 2010. It's in early access though, and needs some work. store.steampow...
You may know this already but a game called "Incursion Red River" just released a few days ago. It's early access and discounted until the 22nd. Gameplay is "Exclusively single-player and co-op" and it has generally good reviews, basically a PvE version of Tarkov from what I'm seeing.
