Lol if it was cod them we would have campaign, multiplayer, and zombies. No, instead we have story (campaign), crucible (multiplayer) which has weekly changes plus the iron banner that enables power advantages plus the trials of osiris, prison of elders which also changes weekly and has 4 different difficulties each with their own set of rounds and modifiers, and 2 full raids. CoD doesn't doesn't have as much to do in it as destiny. It's successful, yes, but these 2 games are world's apart in terms of shooters
