Greetings!
Below is not set in stone but designed to give you an idea of what we intend to do. As some of you have noticed, we're not exactly "rushing". Like many of you, we want to take the time to create a truly massive RTS that is in the spirit of ground breaking games of the past (Total Annihilation for instance).
1Q2015: Mantle / DirectX 12 prototype build. Demonstrate what we can do (read, thousands of units across a world) if we're unleashed. (complete)
2Q2015: Founder's Program Phase I. Experienced RTS players with high end hardware under NDA invited to join. (complete)
3Q2015: Founder's Program Phase II. Benchmark build made available to public, basic single player AI is now in (good enough to provide a reasonable challenge already). Map editor tools provided. Official DirectX 12 build (the map editor won't work on DX 12 yet though). Founders will get coupons for additional keys to share with their friends to help us build up the community.
4Q2015: Early Access. At this stage, the game should be pretty far along gameplay wise other than being only 1 faction and art assets still being rough.
After that, it's TBD.
