Avoid the "Corporation" vans who will do anything to stop you. Follow the Signs to escape. You need to get through 2 tunnels to open the Railway crossing. Once the crossing is open, head through and keep following the signs until you have crossed the second railway crossing and made it to safety.
Use ARROW KEYS to move, SPACE BAR to use HANDBRAKE. Collect the M's to get more FUEL and the SPANNERS to REPAIR your car.
