It's impossible to choose starting locations since the TS engine simply doesn't have this capability, but if you want to play against the AI together with other human players, that's exactly what the Comp Stomp maps were added for. On Comp Stomp maps all human players start on the same position as an AI player and all human players are supposed to send their MCVs into the teleporter that's right beside their MCVs (just like in DTA 1.11's trailer video, if you've seen it). Read the ReadMe file for more instructions.

The closest thing to a manual that DTA has is the ReadMe file, although it doesn't describe everything. I'll add some more things to it later, but it's kinda difficult to figure out what to add to it and what not to add...

Ahh, thank you very much! I've wondered what these strange things on the compstompmaps were, didnt know that these are teleporters . Well, this will work just fine =)
