Because the RTS engine has been completed, with a bunch of levels done. (they are a ton of fun) - I had been focusing on the RPG and other aspects of the game.
Rest assured, i'll be posting more RTS combat (and improving it GREATLY over the coming month or two). More to come for sure.
In the meantime here is some action from a level I prototyped (it continues to improve greatly so consider this a Work in progress even now.)
