Moving into America, the Neo Zeed have control over an army base. The gameplay gimmick with this part of the round is that you can be either in front or behind the fence. To change which side you are on, just somersault jump. Enemies behind the fence will not be able to hit you if you are on the opposite side of it, but you can't hit them, either. This section also introduces new enemies: soldiers, who are armed with guns and grenades, and a stronger soldier who has a flamethrower. He takes more than one hit to kill, unless you have the power-up.

There are also a few dogs that will attack you. These dogs can only jump around, and take one hit to kill, but due to how fast they move along with the soldiers shooting at you, it might be worth doing the shuriken spray to kill everything quickly. A single flamethrower soldier guards the exit to this section.

The second part of the stage takes place in a plane. The main hazard to look out for here is the doors. Throughout this section there are several doors which open and close, falling through a door means instant death. There are several soldiers also inside the plane, many of which are strategically placed so their shots will make you fall through a door if they hit.

The aim of this section is to get to the top right corner of the plane. To do this you'll need to make use of several moving platforms, along with taking out all the soldiers. A final moving platform will take you up to the top right, where you can jump over and finish this section.

The boss of this round is a supercomputer. The supercomputer is well protected, as it can hide itself in a thick armor shell. In addition to this, it is also guarded by two laser cannons. One of the laser cannons, located to the far right, doesn't pose much of a threat. But the other one will follow you around and fire. You'll have to quickly move left or right to avoid being hit when it fires.

The brain of the supercomputer will occasionally rise up out of the armor shell, which is your chance to hit it. It is the only way you can hit the boss, and the brain only stays up for a few seconds. Try luring the laser cannon to the left, then making your way back to the right as it fires so you can get a hit in on the brain. After taking enough hits, the brain will explode and the armor shell will fall apart.
