Super Point Trick
On certain levels in Rampage there are screens that have rivers. Sometimes a tank will also appear and dive straight into the river! When the tank is submerged and is crossing the river underwater, move your creature to the opposite side and punch very quickly. When the tank tries to come up, you will score numerous hits and get unlimited points until your player accidentally eats a person or if you fail to punch fast enough. You can score as many as 400,000 points per board this way and it can be repeated.
