Part 1
After landing by parachute on the lower left corner of the map, you must start out by getting over the barrel to your right. Since you can't jump, shoot your grappling hook at the ceiling over the barrel and swing across to the other side.
You will see a soldier above you. You can either climb up to attack him, or wait for him to drop down to you and shoot him as he falls. You have no health meter at this time, so contact with an enemy is immediately deadly. Soldiers always hesitate for a moment before dropping down. After he is defeated, he will leave a bullet behind. Be sure to collect these bullets whenever they appear, in order to increase your level of experience and build a health meter.
While climbing up to face the next soldier above, you must find portions of the platform that are not lined with barrels. While you can connect to any portion of a platform, you cannot pull yourself up to the top if barrels are in your way. Use the platforms around you to reach the next soldier, defeat him, and collect the bullet he leaves behind.
When the coast is clear, pull yourself up to the door marked with the A on the map. This is a communication room. Walk to the console, and the scene will switch to the transmitter screen, where you have two choices.
- Communicate: MA-1 tells you about the importance of communicating with your allies in order to get important information. It also causes new pathways to open, such as the door to the interior portion of this stage.
- Wiretapping: One soldier warns another about an elevator, referring to the elevators found in the interior portion of the stage.
Once you are done, head outside and drop to the location marked B on the map. Bear in mind that all previously defeated soldiers return when you exit a room. Stand near the edge of the platform, and firing your grappling hook at the lamppost. Then swing across to the platform on the opposite side. Then drop down to the ground level.
Walk to the right, and you will face a soldier with a large gun. He squats down until he's ready to fire, and takes several shots to defeat. Collect his bullet, and then climb up to the platform above. Another soldier will be hiding behind a barrel to the left. He will only be vulnerable to attack when he stands up. If you defeat him, he will fall down to the left, so you won't be able to collect the bullet he leaves behind.
Instead, head to the right. A door will open, and another gun soldier will step outside and squat behind the barrel. Shoot him when he stands up. Climb up to the location marked C, and stand on the platform above. You'll have to shoot your grappling hook at an angle to the platform above. Wait until the soldier there finishes firing, and then pull yourself up to the platform and shoot the soldier before he has a chance to attack.
Time your approach before the next two soldiers so that you pull yourself up right after they have fired their gun. You can collect the bullets they leave behind by firing your grappling hook straight ahead as the bullets bounce. Then climb up to the door marked D on the map, and step inside.
