I am looking for a addon or some gamemode that is sandbox, so exactly sandbox or a mod that allows players to make and manage teams. So like someone can have a red team a blue team, or they could just go on their own. Does anyone know of any team mod?
Uhh, Evolve (an admin mod) lets you make teams and adjust what weapons it can have. You can change team color, but to make an actual structured team, you need to learn Lua and make it yourself.
