Overwatch's limited-time mode, Uprising, is returning this year, and Blizzard shared a few more details about it today. This is the same King's Row mission as last year, but now it has a new name and modes. It's now called "Overwatch Archives," and you can play in Story Mode or All Heroes Mode. Story Mode is basically a replaying of Tracer's first mission in King's Row, with four heroes available: Tracer, Mercy, Reinhardt, and Torbjorn.

All Heroes Mode, as its name suggests, lets you play the same King's Row mission but as any hero you want. Regarding the new name, Overwatch game director Jeff Kaplan said in the video above, "The idea is there are all these cool past moments in Overwatch history, and by going into the archives we can re-live those, and Uprising was just one of those events."
