by Warner Bros. Games and Turtle Rock Studios have released a launch trailer for Tunnels of Terror, the first post-launch expansion for Back 4 Blood. The trailer shows the new playable Cleaners, Ridden Ridden and Ridden Hives PvE activities of the DLC.
Tunnels of Terror adds two melee-focused Cleaners: the defensive Sharice and the aggressive Heng. Sharice is an ex-firefighter who wields an ax – her passive buff increases armor plates. She also has additional trauma resistance and increases overall squad health.
