Years ago, I ran superhero game set during World War 2 in the Pacific. The Japanese Empire vs Allied supers. It was one of the shortest games ever played with the Japanese supers wiped out in two turns.
I thought I'd give the Empire another chance. Armed with a super weapon (code named Death Blossom) hidden on a small Pacific island, their revenge was at hand! The missile would launch in 6 turns.
Turn one was filled with long range shooting. The Japanese soldiers fired 3 volleys at the US soldiers downing quite a few, while overhead the flying supers of both sides took to the skies.
The Liberty Legion was able to attack the missile tower and disarm the missile by turn 4. It wasn't the grand revenge the Imperial forces wanted but they had done better than last time.
