Left 4 Dead 2 is an incredible game. Lots of great coop experiences with friends and randoms, and the odd troll. Also lots of fun in singleplayer. Back in the early 2010s I got to 100% achievement, but a few years ago they released more content and more achievements.
I'm replaying the campaigns on Advanced difficulty for the first time in about a decade!
