GTA V Online Halloween Surprise on now!

I am already wearing the Pumpkin Head mask

Direct from Rockstar:

From now through November 16th in GTA Online, special Halloween treats will be available to the residents of Los Santos and Blaine County on PS4, Xbox One and PC. And no tricks here – once acquired these special items will remain in your inventory, even after November 16th.

Show your dark side while getting around in the Lurcher Hearse and the Franken Stange – both available for a limited time only, along with 20 ghoulish new Bobbleheads that can be added to the dashboard of any customizable Lowrider.

Strike fear into your opponents by donning one of the horrific new masks now available in the Monsters section of Vespucci Movie Masks. 30 Spooky new styles of Face Paint are also available to help you get into the spirit of the season.

Enjoy thrills and suspense with the lights out in this tense new Adversary Mode for up to 8 players. Run, hide, and fight to survive in the darkness as the player designated as the Slasher stalks their prey with a Shotgun. Use your new Flashlight to navigate if you dare, but be careful not to reveal your position or you’ll quickly become prey.
