I just had the CRAZIEST idea what if there was missiles in the game. There could be missile silos. A system could could be set up where one person could suggest a launch, after they find a place where they wanted to destroy (like an enemy base), the team would vote for yes it no if over 50% agree then it goes off you would select a place on the map where it would go. Five people would need to be at the launching solo at once to make a suggestion and stay until launch is detonated or suggestion is declined.
You would only be able to launch a missile once every ten minutes.
