The date is fixed now.
Brigitte, a daughter of Overwatch‘s chief engineer Torbjörn has been teased through several posts before being officially confirmed. She turned out to be of a Support class, with a rocket flail and a handy energy tower shield, a worthy squire to the big man Reinhardt, as established by the lore. She’s been out on the test server for a while, and now we know when she’s coming to everyone and the 27th Overwatch hero.
Brigitte is coming to Overwatch on March 20th, complete with skins, jet-powered flail, flashy shield and all.
