It has absolutely nothing to do with modern warfare 1 or 2.
Still has abysmal netcode, and the worst thing I've ever seen cod implement is RNG recoil or visual recoil. Combine these with the fast TTK and the game is a complete and utter train wreck. Designed like shit. Every gun is a joke except for the m4 and mp5. Cods more casual than its ever been and that's saying something. It is not fun whatsoever, gunplay boils down to who the server and rng gods are favoring at the moment, so instead it's just all about who can spawn kill and hold power positions to kill anyone who runs around a corner. The ground war mode is an infinitely shittier battlefield 3.Such a godamn letdown.
