In this game your first test is a training course. If you can complete it you will unlock weapons. You are running the entire time which makes the task even more challenging. The course teaches you to jump and shoot and move. Collect coins to spend in the play store, grab extra lives and even more time. You will have to get through the obstacle course while killing enemies that appear on the course and in the sky. Everything get's serious once you defeat the trainers course. You are thrown directly into the real deal where you have to collect three coins to earn one fireball (which is your ammo).
