The fourth sequel of the Demolition City game series offers a new mechanic different from its prequels. In Demolition City 4, the core gameplay is the same, demolishing structures using explosives such as dynamites. However, instead of city settings, there are seven levels to play on. In each level, there are various structures which you are to demolish. The structures in the first level are easy to demolish. But as you level up, they become complex and tougher and harder to take down.
The structures are made of wood planks, basic metal pipes, marbles and steel pipes. The explosives that are available to you are sticks of dynamite, RDX steel cutter, PCD-200, RMF-1000 and gasoline barrel. And when you blast off structures, make sure that all debris will fall below the borderline. Go to these guys site to know more about the game and for more techniques.
