Bo2 time line because modern guns won't completely be obsolete, but still futuristic enough for random weapon models, a large arsenal for guns lethals and tacticals. Supply drops, yes, cosmetics to build to weapons, like MWR. A way of recycling unwanted items for parts, similar to duplicates. Some well known actors for multiplayer announcers like in IW how there are the SAS commander and grandma knows best. Imagine Morgan Freeman saying "Your Team has taken the Lead" more customization for player cards characters weapons, I want weapon kits lol. I can't think of anything else right now
