Clash at Demonhead/Route 22

Description
Assuming you entered from the right, a group of enemies will be falling from the sky. Remove them and proceed to the left. Shoot all of the enemies that you encounter as you go, including more falling enemies, some bouncing enemies, and insects that drop when you pass beneath them. Jump up to the platforms to reach the screen above.

On the next screen, you'll see a message outside of a hut. The commander invites you to join the team behind the mountain when the operation is over. Step inside the hut, and you'll enter Susie's Gold Exchange. As long as you have some gold bars, and you possess at least one Shop Call, you can enter. In exchange for a Shop Call, you can select one of two mystery amounts, and Susie will exchange all of the gold bars in your possession for the price on the amount you selected. So for example, if you have 10 bars, and the amount you selected is $500, you'll earn $5000. No matter what price you pick or how much gold you have, you cannot exceed $99,990.

When you are done at Susie's, jump up to the wall on the left, and begin climbing up to the next screen. Start walking to the left. You'll encounter one bird who drops when you pass below it, followed by several tall men with guns. Clear them out of the way, and then press to drop through the platforms and reach hole to the screen below. In the final screen, shoot the two large jumping enemies before leaving the route through the left exit.
