Z was the Bitmap Brothers RTS with no mining and no base building: you take flags, hold territory and your factories speed up.

OpenZ brings it back in 3D for free. Version 1.2 adds the blue side, with General EvilZod and his own briefings, plus a Unit editor where you set up both teams on an empty field and watch them fight.

Windows, with experimental Mac and Linux builds.
