If you jump onto Overwatch's PTR, you can play the brand new map, Oasis, right now, sprinting across its busy roadways and bounding on jump-pads.
Now everyone's chilled out with her a little bit, it might be a good idea to brush up on your Sombra Overwatch skills. That link has got you covered.
Oasis is a Control map and it features a jump-pad, allowing players to leap up to perch on an elevated platform above the point, with the trade-off being that it makes you a tempting target for any Widowmakers with their eyes on the skies.
Elsewhere, there's actual traffic on the roads, so you have to be careful not to get mowed down when legging it across.
You may only be able to access it via Custom Games currently, so keep that in mind if you can't find a game. No doubt it'll be slotted into rotation soon, though, at least in the PTR.
Players are currently reporting issues trying to get into a game, however, so be prepared for a few teething problems. No doubt Blizzard will get it all working as intended soon.
