Overwatch has kicked off its regular annual Halloween promotional event, Halloween Terror. The seasonal event will operate through October 31, and brings with it a bunch of new spooky and kooky skins and other cosmetic items to unlock through loot boxes.

Blizzard has been teasing the event with some unveils of the new skins, including Pharah and Moira, Doomfist, Wrecking Ball and McCree, among others. The new trailer reveals several more like Bride Sombra and Slasher 76. It's all styled after a haunted house, with the viewer's perspective trying to escape the various monsters' clutches. As advertised, the 50 loot box bundle includes a bonus 10 boxes during the promotion, for those of you hunting down skins.
