A soulless, regressive successor to Left 4 Dead that just doesn't have enough polish, visual flair, atmosphere, or technical finesse to impress or stand-out from other zombie-themed games or even co-op shooters, even the visuals are underwhelming and painfully subpar compared to its predecessor which utilizes decade-old tech. There can still be some fun to be had with four players, but the excision of mod support in favor of cosmetic microtransactions and DLC pretty much kills all of Back 4 Blood's substance and replay value and you'll be going back to Left 4 Dead before you know it. A huge disappointment that proves Turtle Rock could not have gone anywhere without Valve's influence, and may God have mercy on them if this is bombing like Evolve did.
