Update: 

The update has now gone live, with an update that replaces Loot Boxes with glowing jack-o-lanterns that include 100 new cosmetic items. All boxes will include at least one item from the Halloween 2016 collection. The update also includes the first co-op PvE brawl: Junkenstein's Revenge. You and three players will team up against Dr. Junkenstein (Junkrat), Junkenstein's Monster (Roadhog), and others, to defend the Adlersbrunn castle from wave-based zombie attacks.

Original Story: 

Rumors surrounding Overwatch’s upcoming Halloween have been circulating for quite some time now, but the strongest piece of evidence popped up overnight in the form of a screenshot taken from its Taiwanese website.

The screenshot shows a Halloween-themed event is expected to take place on October 12th in Taiwan, which means we should expect the update to hit sometime later today. According to some leaked patch notes on Blizzard’s Korean Internet Gaming Rooms (IGR), the Halloween update will become available at 11am PT / 2pm ET and will weigh in at 1.74GB.

The image, which showed both Roadhog and Junkrat wearing their respective Halloween costumes, was taken down a few minutes after it went live. Fortunately, some eagle-eyed Reddit users were able to capture the image in order to give this report even more credibility.

The upcoming Halloween update will mark the second major event to take place in the world of Overwatch. The first event took place over the summer as Overwatch celebrated the Summer Games, which gave us a handful of new costumes, emotes, and more. Its launch didn’t go without a few hitches as Blizzard’s servers suffered from a DDoS attack during its launch as well as its ending.

If Overwatch’s Halloween update does launch today, we’re hoping Blizzard can ensure a smooth launch as we can’t imagine a better way to spend the holiday than by unlocking numerous costumes for multiple characters.
