A leaderboard is included for Endless Night to "commemorate those who last the longest in their fight against the evil doctor".
There's also a new PvE based event called Junkenstein's Revenge, where you can shut down the competition in a spooky surrounding.
Make sure to pick these up either in Trick-or-Treat loot boxes or by purchasing them with in-game currency before the Halloween Terror 2017 seasonal event is over. Players will take on waves of enemies and bosses trying to assault the castle doors.
The leaked skins from earlier in the week have been proven to be accurate.
On the skin front, there are plenty of brilliant new outfits to unlock, including a Dracula skin for Reaper, a Van Helsing skin for McCree and a Cultist skin for Zenyatta. With more heroes available (originally just Ana, Hanzo, McCree, and Soldier: 76 were available), you'll get a loot box for playing and completing 12 waves. Overwatch players can choose four additional heroes for this mode: Genji, Torbjorn, Widowmaker, and Zenyatta.
If you missed out on last year's skins, you've got another chance to get them, too!

Hell, Zarya even got an awesome skin that looks pulled right out of the 1980s. New skins, like Symmetra's Dragon skin, remain at typical 3x event prices - 3000 credits for a new legendary skin. It's identical to past year: Pick one of four heroes and hold the door against a horde of AI-controlled robot goombas while minibosses occasionally show up to wreck the party.
