During the opening ceremonies for BlizzCon 2016 Blizzard had a few big announcements. For one Overwatch is getting a new Arcade mode as well as a new map called Eco Point based off the character Mei.
Arcade mode, Eco Point, and the newly announced character Sombra will all be playable in the public test realm next week. Arcade mode will feature regularly rotating alternate game modes and chances to score new loot as well as one v. one and three v. three play.
Along with Eco Point Blizzard also announced Oasis, a Desert themed map launching in December.
