Surely U could do a shortened version of the red war campaign. Have the first mission that leads to the farm. Heck bring the farm back. I always loved it. U could put Hawthorne, Ada, xur, Eva, Tyra. And the football pitch back in state. Loved it more than the tower tbh. Anyway, U could have the missions of red war that were on edz, Nessus and the last city surely. As for ikora on io and zavala on titan. Surely just the cutscenes would do.
