Blizzard has officially revealed the Overwatch: Uprising event that kicks off today and runs through May 1st. Players "celebrate the Overwatch Legacy" by taking part in Tracer's first mission to London with the action taking place on a modified version of the King's Row map.
The event will, of course, feature loot boxes with new items in them that are themed to the Uprising event. Items include new skins for Mercy, Tracer, Widomaker, Genji, McCree and others. In addition, every box will contain at least one skin, highlight intro, emote, spray or player icon from the event. Credits can also be used to purchase the items from the shop.
The event is four players heading 7 years into the past and playing at Tracer, Torbjorn, Reinhardt or Mercy.
You can read the event details on the Overwatch site.
