Despite wanting to create a wholly new experience, everything from the co-op action to the acclaimed AI director is returning in this improved spiritual sequel. The new special infected aren't the only thing that Turtle Rock is trying to improve upon from its Left 4 Dead roots. This makes the game tuned more towards mowing down hordes than finding a safe house, with at least one team member saying that the game was all about " kicking zombie ass." This doesn't preclude letting players playing as mutated infected such as the human bashing Tall Boy and the bile spitting Retch. The game's survivors are described as hardened veterans of the undead outbreak, with some of them being immune to infection. In a new official video, Turtle Rock details its vision for Back 4 Blood, and it's clear that the team wants to move forward from where Left 4 Dead started.

The team then went on to work on Evolve with 2K, which stumbled out of the gate in 2015 and never fully recovered. Both Left 4 Dead and Left 4 Dead 2 were big success stories for all involved, but an internal conflict between Turtle Rock and Valve caused a split.

The team, which was known as Valve South under the publisher's ownership from 2008 to 2010, rose to prominence with its original pair of zombie FPS titles. In a recent video, Back 4 Blooddeveloper Turtle Rock Studios distanced its new game from its work with Valve on the Left 4 Deadfranchise.
