The Unreal and VR version is now on the main branch.
You will be able to select the version you want to play when you launch the game.
The Unreal version can be played with or without VR, you should also be able to swap between versions without issue.
The Unreal version is still in Beta, so please report any bugs / issues to the forums.
Both versions will kept up to date.
The reason for the Unreal port was not only for VR but it will also create an easier path for a console port.
Thanks for all the feedback and support.
Cheers,
Steve
