That's sacrilege, that game doesn't even come close to the quality of Left 4 dead series and suffers from just about every problem that plagues so many modern games.

Back 4 blood was just another "live service" game that stirred up hype, released in an extremely buggy state, poorly balanced, with terrible AI that was never fixed, without mod support or community servers. They cashed in on the initial surge of popularity, cashed in on the DLCs, and then it quickly died off because it didn't have any of the charm or reply value of the games they claimed to improve upon.
