Monster Jam is an easy game to understand- all you have to do is destroy everything in your path. You start out with the basic truck, which can be upgraded as you smash more and more things.
There are various stages- the first stage takes place outdoors while the second takes place in a mall and so on. As with the stage, the objects you have to destroy varies- outdoors there were pylons to destroy, indoors you have mall vendors to break.
If you collect seven of the special items, you get a new truck. Keys to play the game are the arrow keys to move around and the space bar to just.
