Thanks, I had no idea that was enabled.
I'm in the same kinda friend group, and we are always trying to find that next coop game. I usually check gg.deals daily with a the coop feature selected.
We just played free Demo of Toxic Command it was fun for a weekend night. We have played all the Killing Floor games, and I personally think this one could be just as good.
Here are some other games we always go back to, in no particular order.
Have fun!
