This has probably been done before but I had some crazy ideas for firefight
Ability to add a Zealot Team and Drones to waves
Option to enable Friendly Elites(Making Elites be able to fight with spartans)
BOBs every once in a while will be dropped,Despawn after a while.
FIREFIGHT VERSUS IN MATCHMAKING!(I've been wanting this forever!)
(note all of these would be in a new DLC,Some would be Hazards instead of adding by using the wave properties,)
My ideas,Anyone else have some?
