I wanted to ask if it's possible to play in co-op mode? I tried it once last week, and when my friend tried to join me, he couldn't! I'm wondering if anyone else has tried it recently? It's a mode I've never actually played before, haha, and I was just hoping to give it a shot. I'm going to try again today, but I wanted to know if there's anything different I need to do. I was thinking it might have something to do with the anti-cheat system, but that wouldn't make sense.
