High Roller Wrecking Ball skin is the next revealed cosmetic for Overwatch's Storm Rising event. Storm Rising is the next Overwatch Archives mission and will allow players to once again travel back into Overwatch's history.
Overwatch Archives' skins are usually based on characters past, so this must have been Wrecking Ball's attire while in Junkertown.
High Roller Wrecking Ball
The event seems to take place some time after the King’s Row mission. Reinhardt recently had something happen to him so he is sidelined. The mission will have Tracer leading with Mercy, Genji, and Winston as support. It looks like you will be hunting down Doomfist or his shell company in Havana, Cuba.
The Overwatch event will be made available on April 16 through May 6.
