Outbreak had a very unique approach to cooperation against zombies. The gamemode was very friendly to new players as the infected could only use melee attacks and there were different mini-bosses to discover and defeat. On top of that, it seemed very well built judging from the cutscenes, animations, and especially the backstory. I feel as if new players are really missing out on such a well built gamemode, and some of us really want it back. I understand the focus of Rainbow Six: Siege is PvP, but Outbreak was a really unique change of pace to us all.
