Making the lights on Night maps as a destructible asset could be pretty cool, as the Predator could make it almost pitch black to where the Fireteam is forced to use night vision and cooperate more efficiently.
Make a separate queue for night maps as Predator, so you can either play on day maps or night maps. Fireteam don’t have a choice to choose which one.
Torches, flame or flashlight could be cool idea to add in too.
