I have lost all of my friends

Marathon is a great game, been having a blast majority of the time, but unfortunately this directly has lead to friction between me and my friends. due to the lack of quads, the 4 of us can’t ever all play together, and given the fact that out of all of us i work the most & can’t normally be on until after 5 most days, i am the one left out. I have had plenty of success with squad fill/solo, but still i just miss playing with & talking to my friends. i feel isolated from the group now and it’s honestly a pretty horrible feeling. i really really hope quads are added in the near future despite any “balancing” issues people think would come with that.
