One day ahead of Friday the 13th's physical release for PlayStation 4 and Xbox One, developer IllFonic is rolling out a new update for the survival horror game. Today's patch adds some new content in the form of an additional map, counselor, and Jason, along with the usual assortment of bug fixes and gameplay adjustments.

Both the new map and Jason are taken from the film series' fourth installment, Friday the 13th: The Final Chapter. The map is based on the Jarvis House and its surrounding premises; Jason 4, meanwhile, comes outfitted with a pig splitter as his weapon and can run. The update also adds Mitch Floyd as a new playable counselor. You'll need to be at least level 24 to unlock Mitch, while Jason 4 unlocks at level 44.
