Turtle Rock Studios is a giant, emphatic oh-for-one with major releases after re-venturing out on its own.

This isn't a new story but you'd be forgiven if you forgot the original. In March 2019, Turtle Rock announced Back 4 Blood -- another cooperative zombie shooter. It was painfully light on details.
