Is it possible to have two or more heroes per team, or can there only be one? Thanks.

I know you can do AddUnitClass(REP, "rep_hero_obiwan",1, 4) but if you mean two heros functioning as heros at the same time, I was kinda wondering myself if that was possible.

Theoretically, you would do it by copying the hero line for the side and putting another one in. I have never tried this before, but I think there would be an issue with the hero unlockage. It would get confused about which hero to ask you to be, or it would ony display one, and give you both in the select screen. I do know that if, say, you set Yoda as your hero and then add him on your team, when you spawn as him he will function as a hero.

No, each team can only have one hero class.
