Blizzard will open a giant loot box on stage at BlizzCon

There’s a mysterious event scheduled during BlizzCon.

The Overwatch developer is planning to open a giant loot box on stage at the annual event. What’s inside? We don’t know. If you’ve got our luck, it’s all sprays. The event, called Overwatch Presents: What’s in the Loot Box?, is scheduled for 5:15pm PT on BlizzCon’s Epic Stage on Nov. 3.

“Help our intrepid hosts as they attempt to unravel the mystery behind the gigantic Overwatch loot box that found its way onto the Epic Stage,” the schedule says. It really could be anything, but with all the work Blizzard will go through to craft a ginormous loot box for BlizzCon, it’s got to be something good.

BlizzCon is held Nov. 3 and 4 at the Anaheim Convention Center in Anaheim, California. The annual event features all of Blizzard’s titles, ranging from Overwatch to World of Warcraft. The event’s whole schedule was recently put online, and Blizzard will likely reveal a ton of surprises during the show.
