Co-Op FPS Recommendations?

[KeplerElectronics]

Hey all!

Recently my brother and I played through most of the Halo MCC co-op, and are looking for something new that scratches that itch.

If anyone knows any good co-op FPS campaigns, please throw them in this thread! <3

left 4 dead 2 was a great coop campaign ive done with my lil bro once upon a time- not really as deep in story or scale, but its a bit of chaotic fun.
