what controls? I played it no camera controls, just camera lock on the target, and something like with cam rotation but i dunno how to make one like this... i can cam lock, apply cam rotation, even 1st person and 3rd person, on units\heroes...

I tried making my own in 3rd person but the rotation sucks
