Bad Dudes/Stage 2

You begin stage 2 riding on top of a truck riding on a highway. The zone will scroll slowly as time passes, and you need to defend yourself on the many waves of ninjas. While falling down isn't instantly lethal, you need to jump to the roof as soon as possible, as you won't be in a position to defend yourself properly, and take significant damage.

When you see the red ninja, defeat him quickly and pickup the nunchaku.

Several seconds after auto-scrolling to the front of the truck, the truck will slow down and stop. The camera will scroll one screen to the boss fight.

Boss
The boss is equipped with two razor claws. He will leap into the air, and walk back and forth.

The first weapon allows defeating the boss quickly. Crouch in the center of the lower ground, and attack when he gets close. He will jump diagonally up when injured enough, before trying to approach from the ground again.
