We say "more" because Blizzard has already revealed costumes for two popular characters: Reaper gets into the Halloween spirit dressed as Dracula, while McCree goes vampire hunting as Van Helsing.

The new leaks, which come courtesy of reddit user Mnemosynaut, give us a glimpse at Mei, Zenyetta, and Symmetra. Mei transforms into Jiangshi, which is a Chinese "hopping" vampire. Zenyatta goes as a Cthulhu-inspired Omnic. Finally, we see Symmetra as a Middle Eastern fire demon. We don't know if the Halloween makeovers are limited to just these characters, but you won't have to wait long to find out.
The Overwatch Halloween Terror 2017 event begins later today, and will wrap up on November 2nd. You can expect to see loot boxes dressed up as jack-o-lanterns and 50 new items to collect during the event.
