Here's a thought, an in-game chat box that shows all the people online in the region. You can talk to them and see who wants to do a certain map without having to go on forums. Get a full group and do all the easter eggs. I love doing the easter eggs, but I can't seem to find anyone who wants to do the same maps as me. Another idea, why not have a form of scavenger perk. Maybe for every x amount of zombies killed you get another magazine or so. That's all I can think about, and even if I don't win I wouldn't mind having those features added.
