Hakaiou King of Crusher is a 3d beat'em up game with a curious sense of humour.

The whole game is based on the premise that the salaryman will stay alive so long as he is crushing things. His life or energy bar continuously depletes without the destruction. Another bar records the cumulative amount of damage he's done in a level. If he can reach the end of a level after doing a sufficient amount of destruction, he will transform into a larger even more powerful version of himself and start a new level. There are 18 levels in the game that will see him change into a werewolf like ogre after being bitten by a Doberman to morphing into a Godzilla like monster after being struck by lightning.

At first people will just run away from him in horror, but as Tokyo's destruction mounts, the police and armed forces are sent in to destroy him with tanks, helicopters and jets and they can inflict serious damage to him.

Ultimately, he becomes so powerful that he sprouts wings and takes his carnage to New York City on a mission to destroy the Empire State building, the Twin Towers and even the Statue of Liberty. Lady Liberty doesn't take this lying down and gets off her pedestal to give battle! It's an ending you have to see to believe!

Most of the crushing can be done with punches, kicks and head butts, but there are also two power moves available that will change with each incarnation of him. When he's small he can do leg sweeps and back flip attacks. As Godzilla he can do sweeps with his tail and breath fire. His winged version wages battle in the air with fire breathing and death rays.
