The trailblazing Left 4 Dead and its 2009 sequel redefined cooperative shooters, carving out a new path in the genre that later paved the way for countless co-op-centric experiences. Despite their best efforts, though, no development team could recapture the unique thrill of zombie killing in the Valve-owned franchise; as such, the company’s decision to cease regular support on Left 4 Dead 2 marked the end of an era. A much-coveted Left 4 Dead 3 wouldn’t reinvigorate things either, leaving other studios with the task of carrying the torch. But the likes of Killing Floor 2 and World War Z, while admirable in their own right, arguably paled in comparison to that which came before. With the industry still itching for a comparable zombie experience, Left 4 Dead’s original creators took it upon themselves to revisit the genre through the lens of a new IP—Back 4 Blood.
