One of the best games in history just got better. Excalibur NFL Vibrating Football's classic gameplay has been updated with the latest technology. Now both players can control the vibration, making the game even more exciting and more competitive. Realistic 10-yard chains let you measure your march toward the end zone. Steering wheels on either side of the field allow you to move each player independently. Adjustable vibration controls the speed of your runners, helping you maneuver around the competition.
