After dying and going to hell, you learn that Adolf Hitler is trying to overthrow Mr. Lucifer. If you can prove this to the lord of the underworld, he will grant you passage to heaven.
This deeply surreal game's cast is rounded out by colourful characters such as Adolf Eichmann and John Wilkes Booth.
Technically the game leaves a great deal to be desired, but the plot is so delightfully weird that I'm willing to be very forgiving.
