The current pre-release of the client ("pioneer" in the version) is only compatible to itself. So you can only play with other testers. Please be aware!
@KnownSniper , like SC2, it uses points, instead of using mass/e to upgrade (that will require lots of reworks) I can make an entry like using mass to purchase points
@Nomander That was almost the same idea as mine before. I turn land units collision box off and resume it once encounter with enemy . but seemed not good for game performance.
