Overwatch's Halloween Terror seasonal event returns today, and with it comes a pile of spooky new skins and cosmetics, as well as the return of last year's unlockables and the Halloween-themed Brawl, Junkenstein's Revenge. 

The skins include the handful which leaked over the weekend—Satanic Symmetra, Vampyric Mei, and Cthulhu Zenyatta. Like the previous Summer Games seasonal event, skins from last year's Halloween Terror event are also available for unlock, though at the price of normal, non-event skins.
