Start a new game, and fail all the missions you play until you are below -50,000 credits in debt. An FMV will be played, and you will start the game over with a clean slate. Doing this gives you special abilities, the first time it gives you a grid radar, the fourth time it gives you the ability to fire back weapons with huminiod legs while standing. The sixth gives you 2x energy for boosting, and weapons. Have fun!
