Time to buy a couple of spooky cars and get chasing down the slasher.
Players are able to buy a couple of new vehicles, the Albany Lurcher hearse ($650,000) and the Franken Stange hotrod ($550,000).
The update also includes a new Adversary mode called The Slasher, with five maps to play through.
You can also buy a flashlight and get 39 new masks (as seen in the video above) and facepaints, as well as spooky bobbleheads for your lowrider.
Players won’t need to download anything as the content was hidden in the last Lowriders update.
Update: Rockstar has said that the Halloween Surprise will run until November 16 and you can expect details of a special weekend of events soon.
