Arizona Sunshine developer Vertigo Games has announced today that its virtual reality (VR) videogame, Skyworld, will be released this Fall for Oculus Rift, HTC Vive and Windows Mixed Reality (MR) headsets.

Created in conjunction with Wolfdog Interactive, Skyworld is a one to two player title, that mixes turn-based strategy with real-time battles in which you play a king looking over their battle map. From here armies and buildings can be created to storm enemy strongholds, whether that’s in the single-player campaign, skirmish mode or the online cross-platform multiplayer.

So that means when the Windows MR headset does finally launch as a consumer version later this year – there’s a developer kit already available – owners will be able to fight against Oculus Rift and HTC Vive players as well – possibly the first VR title to confirm this functionality.

Vertigo Games first announced Skyworld at the 2015 Game Developers Conference (GDC). It followed that with a showcase of Oculus Touch support that same year, then stating the title would be among the first for the motion controllers. That didn’t happen, instead the studio has continued development, adding another compatible headset that should hopefully help when finding online matches.

VRFocus will continue its coverage of Skyworld, reporting back with any further updates.
