NOTE: BEFORE READING THIS SECTION AND GOING ON, READ SECTIONS 0.0-2.3 AT LEAST BRIEFLY. I DIDN'T WRITE THEM FOR NOTHING! THEY HOLD IMPORTANT INFORMATION YOU NEED TO KNOW FOR THE REST OF THIS WALKTHROUGH.
So, we finally start! First of all, you’ve gotta get used to whatever controls you use. Practice swinging and shooting several times first. You start by floating down with your parachute. Once you land, charge to the right and stop a little before the barrel. Without stalling, grapple diagonally to the platform on which the red guy is walking. As you swing, drop off so you land on the other side of the platform. The red guy will jump down (through the platform!) and when he does so, shoot him and watch him transform into a green bullet. Pick the bullet up and, if you want, hit Select. If you do, you’ll see L=001/005 at the bottom. This means you need four bullets to get a little life point at the upper left of your screen.

Anyway, hook straight up twice then, go as far right next to the barrels as you can, then hook straight up again onto the small platform. There’s a guy on the right side; when he gets onscreen, duck and shoot him, then go pick up the bullet. Then hook up to the red platform, walk left until you’re under the door, then hook up and go right in.

This is a communication room. In order to save time, you’ll skip these rooms if you don’t need to go into them. However, you need to use it this time. Go immediately to the right to the big computer thing until the screen changes to a communication screen. It’ll let you communicate or wiretap. Never wiretap if you want to save time. Not only is it never needed, but it’ll also bring in a bunch of soldiers sometimes. So select the option COMMUNICATE (with button A), and watch the guy talk. You don’t need to listen to him, though, so after you choose to "communicate," just press B to cut him off. You’ll return to the regular screen, whereupon you can go back out of the door.
Once outside, notice the guy you killed has regenerated. Fall down to the left a few times. Now, this is a good place to practice shooting while flying through the air. What do I mean? Go to the right edge of the platform, make the short connection to the right, and press the right button to swing off to the right. While you’re flying towards that guy on the yellow building, shoot him and kill him.

Anyways, kill him and get the bullet, however you do it. Then right to the right side of the barrels, where (gasp!) there’s no platform! Never fear, however. Use the bionic arm to grab the light pole, and swing off to the right. Then walk right, fall off, then fall off the right side again, timing carefully to not get hit by the stationary shooter. Charge right. As soon as you see the stationary shooter, duck and fire at him. Kill him and grab the bullet. Then walk a little farther right until the shooter on the left is off the screen. Hook up at a good time, then get right next to the barrel on the right. Stay right there until the guy shoots, then stand up and start firing like crazy. You’ll kill him. This is known as THE BARREL SEQUENCE. Get the bullet by throwing your bionic arm to the right over the barrel without ducking. Then hook up twice to get to the narrow yellow building. Get to the right edge, then grab the platform above diagonally. If you were right on the edge, don’t worry, and just shorten the connection and get up. Blast the enemy, get the bullet, and get up onto the next platform. Charge left, and duck right by the barrel. As before, blast him right after he shoots. Then get up onto the next platform. Kill that guy, get the bullet, and go up to the door. Enter it. NOTE: IF IT’S NOT OPEN, YOU DIDN’T COMMUNICATE. I TOLD YOU TO! GO BACK AND COMMUNICATE.
OK! You’re inside, which is good, because it was a bit chilly outside (just kidding.) The elevator takes way too long. Just fall off the left side. While you’re falling, face right and grab the third or fourth (either one) platform on the right side (the purple ones.) Once you’re swinging, go to the left, and charge until you reach the barrel. Hook straight up, shorten the connection, and blast down the electric barrier. Drop down, and kill the guy on the right if you want to. Then go to the left, hook diagonally, swing off over the barrel, and drop quickly. This part is a little tricky. Go to the place right in the middle of the barrel and the green platform on the left. Face left, and swing off to the left. AS SOON AS YOU START FLYING OFF THE CONNECTION, GRAB UP AND HOOK UP TO THE GREEN PLATFORM WHERE GUYS ARE WALKING!
If you can’t, you’ll land on the green place on the left. If you do, swing back over to the right and try again. When you succeed, stay right below the platform, and don’t climb onto it until the guy/guys are on the right side, away from you. When this time comes, get up and shoot them, grabbing the bullets. Quickly, hook straight up to the small green platform with a barrel on it. If there’s already a guy walking there, you have to just walk around on the platform you’re on, killing the parachuters that come and waiting until the platform is open. Anyway, you should get there soon. When you do, kill any guy there might be on the left platform. Hook diagonally to the left, and swing in that direction. Keep swinging until you reach the platform right next to the red rock opening. Hook up at this place and swing over to the red rock opening. Charge right, avoiding the bombs and/or large bullets the guy behind the barrier throws/shoots. Once he throws or shoots, hook straight up quickly and shoot the electric barrier. Then drop down, being careful not to be hit. Watch both sides, as parachuters may come in from the right. Kill the guy throwing bombs and shooting large bullets and get the bullet he leaves behind. If you’re not too good at this game, stay right outside of the door with the eagle on it and kill all the parachuters that come out of nowhere. Gather lots of bullets, and if you want to know how many bullets you have and how many you need for another life point, hit Select. If you’re paranoid and/or really not-so-good at this game, get 60 bullets (4 life points.) If you’re OK but not good, get 30 bullets (3 life points.) If you are good and/or brave, go into the door. Whatever you need to do, do it and hop into the door.
This is the boss room. As soon as you go in, charge right. You’ll be greeted by the commander. Once he finishes, shoot the guy who approaches from the right, then hook and climb up onto the platform where the commander (the guy waving the stick thing repeatedly) is. Shoot him and any jumping bad guys. When the area’s open, charge right, kill the guy on the right, and swing diagonally onto the little platform on the right. The thing on the right is the generator. Get on the left side of this little platform and fire away. Each time you hit the generator, a sound will play, and the room will flash. Keep firing. Stop only when a guys approaches from left (these guys occasionally take a shot at you.) If you’re at the left and facing right, fire continuously to kill all jumpers and damage the generators. You’ll destroy it quickly. You’ve just beaten the first level! What’s more, we’ve obtained energy recovery pills! Notice, however, that they’re not pills; it’s a flask of green liquid.
NOTES: IN THE BOSS/GENERATOR ROOMS, YOU DON’T GET ANY BULLETS FOR LIFE POINTS. ALSO, THERE’S A GLITCH IN THE GAME: AFTER YOU DESTROY THE GENERATOR, YOU ARE STUCK IN YOUR POSITION, BUT THE BAD GUYS CAN SOMETIMES STILL MOVE AROUND AND DAMAGE YOU. THIS IS STUPID, BUT CANNOT BE HELPED.
