Immoral Kombat is an arcade game developed by Running With Scissors, appearing just in A Week In Paradise. The only arcade machine is located at Grossman's Arcade. Along with Fag Hunter, Immoral Kombat is one of the few arcade games adapted into a real mini game.
To play the mini game, the Postal Dude must insert two tokens. The setting is similar to those of the real Mortal Kombat video games, and the Postal Dude must kill 40 members from hate groups, terrorists and gangsters to finish the game.
