This would be REALLY really cool. Like Agia Marina is flooded (Or other major areas in Altis), and divers and stuff have to go through looking for survivors, maybe the first floor of all the houses are flooded and you have to swim through through flooded streets etc. Maybe at night, the street lights could be on still. It'd be interesting.

You guys seem to be forgetting that there's collision lights on the outside of the chopper already, but those can be turned on and off. I'm not saying I support this idea, as there's NVGs for a reason.
