Specific Multiplayer

Hi! I’m trying to make a multiplayer game in Unity where there is a team of 6 against 1.
I want to eventually make it so the team of six has like 2 minutes to fortify a base before the 1 guy attacks.

How would I go about setting something like this up?

If there are any tutorials or pieces of info you could give me, that would be fantastic.

Thanks!

well i dont know a lot of this but if you had made a team death match just change it to 6 teams to 1 instead of 1 vs 1.

well i know this is not helpful but it might give it you an idea
