Amphibious Challenge is a game that has you trying your very best to keep different vehicles afloat in the water. You'll have three vehicles from which to choose: A Tryumph, a Dampervan, and a Toybota. It's hard to tell whether one is easier than the other or if they're just for show. Use the mouse wheel to calibrate for play. You'll keep the car afloat by moving your mouse back and forth to keep it from capsizing. You'll be scored based on how long you're able to keep the vehicle upright in water. See if you can beat the high scores and try Amphibious Challenge now.
