This is one of those coin-ops that leapt to fame more because of an off-beat aspect than amazing play. Here the gimmick is that up to three players take control of monsters rampaging through a city full of skyscrapers. Each screen is made up of a static view of a city street.
The monster must destroy all the buildings on the street to go to the next one. Buildings are demolished by the monsters climbing up them and smashing massive holes in them. Sometimes useful stuff, such as good, is revealed, other times it may be something harmful (i.e. poison). Also after the monsters' blood are tanks, helicopters and snipers.
The concept is novel and initially very funny, especially as you beat up the other monsters (either computer- or human-controlled). However, there's very little variety to the gameplay and the items which you can pick up are very hard to see.
In two player mode, it's enjoyable enough, but on your own it can soon becoming boring.
