I suggest adding nuclear warheads to the weapon DLC. there would be three sizes: small which will be 1x1 and 6 blocks long with a blast radius of 1 mile and a yield of 20 kilotons of TNT and a cost of $10,000. then medium which will be 3x3x3 and will have a blast radius of 5 miles and a yield of 21 kilotons and it would cost $20,000.

then large with a blast radius of 25 miles and a yield of 500 kilotons and it would cost 80,000

you may tweak the radius and yield of the bombs as you see fit for the game. thank you for reading my suggestion.
