Sombra has arrived in 'Overwatch'

At long last, the 23rd Overwatch hero has arrived.

The stealthy hacker Sombra entered the Overwatch fray on Tuesday alongside the brand new Arcade mode and Arcade-only map Ecopoint: Antarctica. All three new features were revealed at BlizzCon Nov. 4 and were available to test out on the public test region since Nov. 7.

Sombra is only the second hero to join the roster since the game's release in May, but her unique skill set makes her a much bigger disruptor to the game's meta than Ana, who came out in August.

Sombra can hack enemies to disable their abilities as well as teleport and turn invisible for a short amount of time. She's built for stealth offensive support, with those advantages offset by low health and weak damage output.

Along with Sombra, the new Arcade is taking the place of Weekly Brawls and introducing brand new ways to play, including 1v1 Mystery Duels, 3v3 skirmishes and a No Limits mode with no hero limit (essentially replacing the old format of Quick Play, which will now have hero limits in the same vein as Competitive).

The new map Ecopoint: Antarctica is an Arcade-only map and much more compact than traditional Overwatch maps, eschewing the objective-oriented layout of every other map to instead put the focus on team fights.

The introduction of Sombra has been a long-awaited event for Overwatch fans, with her character being teased in a months-long augmented reality game that leaked out small clues about Sombra.

Her Tuesday arrival was teased on Monday when the patch started downloading -- players received a global message in the game that said "Boop," which Sombra said in her release trailer when she used her hacking ability.
