Killing Floor 2 is great, although I have not played it on Playstation. The co-op survival horror is really a change of pace from other team-based shooters.

I haven´t tried it yet. Is it possible to play the campaign in co-op ?

Honestly, I haven't actually really played any of the free games since Rocket League came out (2?) years ago for free. I fire up Gauntlet every now and then, but that's about it. I always download them all, but its hard to find any that are appealing. I'll give Killing Floor 2 a shot tonight though.
