I actually used to know a card game called thermonuclear war. Sort of similar to war where the highest card wins, but both players take 5 cards off the top and can play them in any order. Also you start out with the 2's being nukes, and will destroy any card they're played against, and once those are depleted the 3's become active. When 2 nukes meet the remaining cards in hand are wiped out and then there's something about flipping more cards off the deck to see who win the round, which occasionally ends up with more nukes coming out with more destruction.

Can't quite remember all the rules around nuke deployment but it was an apt name because quite often both players had all their cards demolished, showing that in nuclear war there are no winners.
