[Update #3]: I've now also added a teaser for Pharah's Enchanted Armor skin, McCree's Undead skin, as well as Wrecking Ball's genuinely amazing Jack-o-lantern skin. You'll find them down below, along with all of the other newly revealed cosmetics.
Overwatch's Halloween Terror event is set to arrive this October 9th, bringing with it the Junkenstein's Revenge PvE mode, a whole assortment of new and old cosmetics, as well as spookier versions of some of the current maps. If you were hoping for something completely out of the ordinary, I'm afraid I'll have to disappoint you as Blizzard is keeping this event fairly light, though there will be a brand new boss in Junkenstein's Revenge, as well as a newly reskinned map to keep us occupied.
As for the cosmetics themselves, Blizzard has now finally started releasing brief teasers for them, all of which you will find right below. The quality of the images and videos is unfortunately a bit low as Twitter has compressed them heavily, but it should still be enough to give you a general idea of what to expect from each skin. Once more cosmetics are revealed I'll make sure to update the list, but for now, have a look at what's coming with this year's Halloween Terror:
You can get a closer look at each cosmetic by either clicking on the name or the image itself - both will lead you to Blizzard's short spin-around preview of what it looks like in-game. So far all of the skins are looking pretty damn good, so hopefully the trend will continue as there are still 3-4 legendary skins to unveil!
Once more details are released I'll make sure to let you know, but until then you might also want to check out the new Torbjorn rework on the PTR servers. I'm not exactly sure what to think about it just yet, but it's certainly a lot more action-orientated than the previous Torbjorn, which I do believe is a step in the right direction when it comes to making him viable on both attack and defense. Whether it will actually pan out as expected, I suppose we'll see soon enough as he's bound to enter the live servers in the near future.
