I finished the main quests which were available in beta. I only had one glitch where I fell through the world. I really enjoyed it. did not group though. I was trying to figure if you have companions like in Ghost Recon Wildlands. I think you do but not 100% certain. =)
I don’t believe you get any companions aside from the drone.
They said they were working on AI team mates, I really enjoy breakpoint.
