As I have many ideas, I'll go through many different ideas I have. I doubt that this will happen, but IF YOU WANT, please feel free to DM me if you want more details.

1. Fighter Jets.
   You guys already have the realistic flight controls in, and I do know that the maps are quite small, and it could be exclusive to the Mauritiana map (or however you spell it, my mistake), since that map is quite large and there could be a conquest variant of it. Possibly fictional fighter jets based on other ones.

2. Extraction mode.
   I've walked around the oil rigs in Clearwater and Paradise, and I've seen that there are many different doors that lead to rooms, but none of them are able to be opened. I figured that there could be a special 8 player gamemode and 4 players per team and they would be able to extract and go into those rooms. The gist of it is that the squad of 4 players would go in during the night and extract the red ore for it to be researched in the Coalition labs, to add on to the lore. The players would be dropped off via Blackhawk and be given a few seconds for each player to pick their class, change their guns, all that kind of stuff. They would have flashlights and night vision goggles (taking inspiration from special forces in the US military). They would then hold their trigger and try to extract the ore before the other "guards" of ORE's military try to find them. The players are given a certain amount of time to extract as much as they can. If they succeed, the helicopter will land and they will be taken back to the Coalition Forces base. If not, the mission will have been unsuccessful and they would have been eliminated by ORE.
   About the maps.
   The various maps that can be in this gamemode will be the doors in the giant tower thing in Mauritiana, the oilrig in both Paradise and Clearwater. And finally, the bunkers in Paradise.

3. Destroy.
   In the lore (if able to be fit in), the war would have almost ended and the Coalition forces would have been getting closer to victory. The Coalition Forces have brought many Apaches (and fighter jets if added) and using rockets that are seen on the Apache's sides, they will be trying to destroy the supports of the oilrigs to destroy them.

Thank you for your time,
