I've been playing Rising Storm 2: Vietnam. It's... actually a lot of fun. Positioning and communication matter a lot more than just a good shot. Taking objectives and supporting your team give a lot more points than kills, which are mostly inconsequential.
My first experience in the game was hearing that napalm was coming, so I dove through a window. I looked back the way I came and saw my entire squad melting and screaming. If you enjoy FPSes, I highly recommend it.
