I NEED HELP WITH MULTIPLAYER SETTINGS

[SCorpA1]

I would like to know how to do team trades (i.e. gold and weapons).

enable share mode at the beginning

and how can the AI always get the dark cannon right away?

dark cannon? i dont knowwhat you mean, but maybe your problem is, that you play e.g. you with 2 bots vs 2 bots, so in your team is one more player, and the enemy players have more startgold than you ?
