Two brothers Tod and Pete went on a summer bike ride in the park. But the trouble is our heroes were attacked by aliens who circled over the park on their flying saucer. Shooting on the wheels they paralyzed the vehicle brothers and attack them. In the game Tandem Pumping you will help them fight off the aliens. You will do this with the help of a pistol that will be in the hands of one of the brothers. While the second changes the wheel, and pumps up the tires, you need to aim the gun at the monsters. As soon as you grab someone in sight, open fire. Do it all quickly, that would destroy all the enemies and prevent them from approaching our characters.
