You are riding a monster truck and you are going to do normal monster truck stuff like destroying anything on your path. Well, most of the time you are going to run over those parked cars with no engine so there won’t be any lawsuit around. :D
You also need to collect some stars on the way while you are at it as they will give you some added bonus points for the level. The terrain is rough since you are going to go through mountains one after another. You should know how to balance your truck to get to your destination or it would end up in the junk within a few seconds.
