After teasing it yesterday, Blizzard released a Preview video of Overwatch's latest addition to its map rotation titled, Horizon Lunar Colony. The preview is part of the One Year Anniversary event that is currently going on and running until June 12th and shows us the first map that will take players off-world.
Here's the trailer:
Horizon Lunar Colony is an Assault Map and home to Winston and provides a bit of narrative context that Blizzard has subtly, but effectively injected into the game. If you're playing the game on PC, you have access to the game right now by opting into the Overwatch public testing region servers.
There's currently no date as to when everyone will be able to play it, but it'd be wise to expect Blizzard to test the map for at least a couple of weeks before it's made available. With almost two more weeks to go, expect plenty more Overwatch news to come in that time.
