A new official short story by Canon Overwatch has been released. Written by senior-era and game story designer Michael Chu, Valkyrie is a first-person story about Mercy, who agrees to the role she plays in the Overwatch organization after it dissolved. It seems that the short story is set shortly before the start of the game and is associated with an event in the game history that may give you a new Mercy costume.
We've gone over the story and summarized the highlights from it below – stop now if you want to read it yourself, without spoilers.
The story begins with Mercy reminiscing about her parents, who volunteered at a hospital in Switzerland during the Omnic crisis and were killed in an air strike one day when she was still young. The story jumps forward to Mercy as an adult working in a relief camp just outside Cairo. She was removed there for two years, ending her term as head of medical research for Overwatch when the organization collapsed sometime earlier. Her reputation was shattered when Overwatch was disbanded and she went to Egypt to help, as Overwatch was "responsible for much of the country's suffering."
Then the story interrupts Mercy to reunite with Soldier 76 and Anna, who have her track record as 76 badly in need of healing. Mercy and 76 are having a heated discussion about the state of affairs ̵
The story goes back to Mercy and the first meeting of 76, broke up. through Mercy's research on nanobiotics (which, history tells us, is unrelated to nanobot technology). They give us some idea of Mercy's research and how it was brought to the fore, with the promise of allowing her to develop healing technologies for use outside the battlefield – which, of course, is not exactly what happened.
Back to the present, the trio is shaken by an explosion at a nearby facility near Anubis and reluctantly Mercy straps in her Valkyrie costume, along with the other two, to go to help with Talon's beating forces. In the midst of the battle, Mercy finds Hanan, a young wreck girl, who recognizes her as Mercy when she uses her healing staff. It soon turns out that he also has to rescue Hanan's brother, who is trapped in a crumbling building.
A mortar hit the building during the rescue attempt and Mercy's suit was badly damaged. She manages to save both children when the building collapses, trapped when the building collapses around her. But 76 comes back for her and eventually everyone survives. Subsequently, 76 and Anna tell Mercy that they are going to continue hunting for the Harvest, which is responsible for what happened that day. Mercy doesn't go with them, but as she continues to work, and as she thinks about saving the two children and how excited they are about meeting Mercy, she begins to reassess the value of her work with Overwatch.
If you want hungry for more Overwatch erudition, the recently announced Overwatch 2 promises to deliver much more.
