We have a preview of the next Ashes build. Not the Thursday build but beyond that.
Go to Ashes in Steam. Go to the properties of Branches, go to beta and type this PW in: AshesSingularity2016
It's the musician branch. It won't stay the latest for long so you'll want to switch to the main branch soon but we'd love to get an idea of stability with regards to graphics/windowed mode/ full screen mode.
