A nuke?
Is that the axis equivalent of the allied grenade?
in that case, this mod rock:
I remember that I made the explosion (after throwing a nade in the water) 20 times larger and added a cooler sound. I also tried to skin the water yellow and red. It didn't work though. I think I got a pic of it somewhere. (my computer fucked up everytime I nuked the map,, but it was worth it)
