You need to deliver tons of rock to its destination and a simple truck can't do it since the rocks are too heavy and too large for someone to put it on the truck. It needs to be rolled over and the only equipment that could do the job is a bulldozer. Fortunately, only you could drive the bulldozer in your company and that makes you one of the best employee in the company. To make it short, they can't just fire you like the other employees they have. Other employees are expendable, but they can't just replace you easily since your skills are hard to find. In this game, you would be delivering a lot of things other than rocks with the bulldozer. There are times when you just need to get to the location. Don't forget that you need to get there on time regardless of what you need to deliver. Your score depends on how fast you are able to get to the location. The hills would make things a little tough for you if you are not up to the task. The game would be harder as you make some progress. Don’t let anything stop you.
