At this year's Blizzcon opening ceremonies, Blizzard quickly showed off a new Overwatch map after revealing that Sombra will finally be making her way to the game soon. The map will be called Oasis and it'll be set in Arabia.
There will also be an additional map, Eco Point, which will be playable in Overwatch's new arcade mode, which will allow for 1v1 and 3v3 matches. Oasis will be hitting the Public Test Realm in December, and the Eco Point map and new modes will be available for testing (along with Sombra) next week.
