I hate when games give you NPC team members. I'd much rather just go it alone.
I was playing Halo: Infinite last night, and I'm coming up on the Command Spire. I could tell there were going to be a ton of enemies there, so I kind of wanted to stealth sneak up and snipe as many as I could before entering the section leading up to it.
Unfortunately, I was coming from that FOB that is right next to the spire, so a bunch of soldiers followed me with a bunch of shouting and guns blazing. There was nothing I could do about it. So I had to completely change up the strategy that I wanted to go with. Guess what. When I got in, I had to face two Hunters at once, and my other soldiers were nowhere around to help me with them.
