The good news is that if you’ve been anticipating these features, then you’ll be pleased to learn that both the deathmatch mode and Junkertown have been added to the game’s PTR. In case you’re unfamiliar, the PTR is the Public Test Realm in which Blizzard uses it as a platform to test out patches and upcoming content for their games.
This means that what players see right now in the PTR won’t necessarily be the same as when it is officially launched, so in a way you could consider this to be a beta of sorts. Also since the PTR is limited to the PC, only PC gamers will be able to take these maps and modes for a spin while console players wait for their final release, which should presumably be in the near future.
Note that this particular update will also be bringing about the reporting feature for console players, so that could be worth looking forward to in the near future.
