Ive played a few multiplayer games and beyond the inevitable lag and typical alpha issues heres a few that ive noticed; HP bars of pretty much everything appear to be slightly below full AA tower attacks ground units ( not sure if this is a feature, could be pretty cool but they dont seem to have any lessened power against ground so its a bit OP if they are supposed to do this) Laser towers seem either too powerful or too cheap ( could be wrong given i havent found any other tower defense structure other than artillery or the close range thang) Anti nuke has the same image as the catapult in construction menu In the advanced bot factory two units have the same name and info, although they do have seperate icons Major delays at times in move and build commands; also can affect attack commands Hope this helps
