Go to course 5. Halfway through the race, to the left,
you will see a stream coming out of the wall. Follow
the stream round to come to a wall with a yellow and
black skull painted on it. Shoot around 5 missiles at
it and it will blow up. (Probably you as well). There
is now a short cut - by-passing the corner. There is
also one other skull on a wall which folds down to give
you maximum everything.
