========INFILTRATOR========It's called infiltrator. The objective is that you must get a certain number of teammates inside the other team's base for a certain amount of time. This could get really fun/challenging if you need to get more than 50% fo your team in the base.
sounds like territories. That being said, infiltrator = spawnkilling.(2 ppl in their base, 2 ppl spawnkilling, since the other team respawns where the objective is.)
