Blizzard has been teasing the second post-launch Overwatch character, Sombra, for months -- cryptic clues and leaks have been floating around since the first extra character showed up. At last, though, she's here. After about a week of public testing, Blizzard has released a finished update that brings Sombra's stealthy hacking to PC, PS4 and Xbox One players. To recap, she's an "infiltrator" who can temporarily become invisible, teleport to a beacon, disable enemy shields with EMP blasts and hack both health kits as well as Torbjörn's turrets. She's who you send in to undermine a stubborn defense before your main assault.
