Map maker of Total TD here; I just released this Tower Defense map. I have a bunch of testers, RL friends, and a couple clans playing on this mini, arcade game launch event that I have created.
Just a shout out to community forum people who may be reading this. I, and a bunch of the above mentioned will be playing Total TD for several hours this evening. So, if you could, log into SC2 and click play on Total TD for some friendly 3v3 Tower Defense.
