While the new update brings some of the infamous terrors from the Saw and Texas Chainsaw Massacre franchises, Dr. Karlov is the video game series' own original character. Described by developers as an “infamous Verdansk urban legend,” he was a scientist who obsessively studied the effects of electricity, running "experiments" on those who came too close to his hideout.

With this update comes the opportunity for players to unlock his electric throwing knife and electric weapon blueprints, as well as a skin modeled after Dr. Karlov's own image.

These bonus skins and weapons are being added in addition to the Leatherface and Billy the Puppet features, including other cosmetic items for your characters and machinery.
