After a bizarre experiment went wrong three common people were transformed into giant monsters (a fifty-foot Gorilla, Lizard or Wolfman), and now you can pick one of them and terrorize the city! In a desperate battle for survival, you climb the skyscrapers and smash the walls with your fists, searching for edibles that appear behind the shattered windows. Grabbing inedible such as TVs and toasters, will inflict some damage on you (your stamina is indicated by the energy bars at the top of the screen. Up to three players can play at the same time. Damaged buildings will eventually collapse into rubble, but leap off when the foundations start to give away - getting trapped in the failing masonry will weaken you! The nation's military and police forces might also bent on your destruction, so try to avoid (or punch) the troops who fire from the windows, and the gunship helicopters that are constantly circling overhead. You can also punch - and be punched by - your fellow monsters. If you lose all your energy, you revert back to human form and, hiding your nakedness as best you can, shuffle off-screen embarrassment.
When a whole block of buildings has been demolished, a new city block appears, ready to be flattened. There are 50 cities, and the monsters spend three days in each one, making 150 different screens!
The game is a joy to play, either in two or three player mode or in single player (the cp controls the other two), offering addictive gameplay and easy enough controls.
Graphics here are colorful and the city blocks are nicely designed, mostly resembling the original (arcades) version. Sprites are nicely drawn and animated, sometimes in a funny way in such, when you fall accidentally from a building the beast closes his eyes etc. The action is not that fast, but overall visuals are pleasant.
Sound is nice too, offering a few SFX (such as when punching an opponent monster, when damaging or flattened buildings) whilst to there is a nice (but rather repetitive) soundtrack during gameplay.
