Okay, this is just an idea I had after creating a shotgun pellet shooting chainsaw at low speed. It drops the pellets down onto people below and though, combining this with trenchwars would make a pretty cool minigame.
So basically pick an ol' Trenchwars map, set some points in the sky where the shotgun pellets would fall from and see the results. The damage could be altered, basically making the difficulty different by making it harder to survive.
This would be like the falling berkerker bonuses mod except the bullets would collide with the roofs of buildings and shelters as long as the speed is about 80 or so.
What are your opinions?
