This level is fairly complex. This walkthrough will go through the basic parts of the level...there are many places to explore that will not be discussed. This is the first regular level to contain Fusion Hulks and cloaked Class 1 Drillers.

• The way that most of the rooms are oriented promotes the ability of the robots to perform surprise attacks. This is especially true in the reactor room, as the curvature of the passageway leading to the reactor room allows the Fusion Hulks there to hit you before you know they are there.

From the entry point, you will have to go through three rooms to access this junction. (As a matter of fact, you can only go to this junction for right now.)

The upper area of the junction is guarded by a Class 1 Driller and a Class 1 Heavy Driller. First, take out the Class 1 Heavy Driller when it comes up. When it does, put it into your sights and destroy it. Then, rotate your ship to the right and slide left. Fire a homing missile when you see the Class 1 Driller and the missile will destroy the driller.

The lower area contains the exit, the yellow door, and the red door. This area is guarded by two Class 1 Heavy Drillers and a Super Hulk. The way the room is structured gives the enemies an advantage. When you go down, first take out the Super Hulk lurking around the exit, then peep around the corner and destroy the Class 1 Heavy Drillers. Once you have done so, return to the upper area and enter the door indicated to access the blue key.

After going through two rooms, you will encounter a set of corridors with purple walls. You will have to find a corridor in the floor to access the blue key. While exploring this area, you may have to take out a Fusion Hulk, a cloaked Class 1 Driller, several Medium Lifters, and an occasional Medium Hulk.

Once you find the area indicated on this map, go around and destroy the Defense Robots and the Class 1 Heavy Driller in the outer area. Then, go down to the blue key room, which is indicated by blue lighting in the floor. Destroy the Class 1 Heavy Driller to your left, grab the blue key, and pick up the shield powerups.

You may access the blue door by the corridor indicated on the map, or you may return to Shaft Junction and go to the room that you destroyed the Class 1 Driller, which contains a blue door.

The yellow key is located in a dead end as indicated on the map.

The big room right next to the yellow key should be cleared before grabbing the yellow key. I have known instances where the enemies in the room have sneaked upon the corridor leading to the key. This big room is guarded by several Medium Hulks, two Gray Platform Robots, and several Medium Lifters.

Once you grab the yellow key, you may access the yellow door by returning to Shaft Junction and heading for the lower area.

Once you enter the yellow door, begin by shooting the ceiling. You should be able to locate two secret doors that cannot be opened. Once you have located the two doors, lay proximity mines right under the doors, and keep going forward. Once you enter the main room, the doors will open. Destroy the Super Hulks and Class 1 Drillers which were not caught by the mines.

Next, go through the main room and destroy any Medium Lifters, cloaked Medium Lifters, and Advanced Lifters that you encounter or the robot generators produce, and find a hole with red lighting. Once you locate this hole, go down and on the next room, destroy the Medium Hulks and the Class 1 Drones guarding the hostage doors. Blow the hostage doors, but don't rescue the hostages yet.

Next, go back to the hole and continue down. Immediately attack the Medium Hulks, Class 1 Drillers, and Super Hulks guarding the reactor. Destroy them all and grab the red key. Also located here are secret rooms with weapons powerups. Each niche contains a secret room.

Rescue the hostages, and return the Shaft Junction to access the red door.

Once you enter the red door, be on the lookout for two things: Fusion Hulks and a secret door in the ceiling. Once you find the secret door, lay a proximity mine. Pass the door and it will open, revealing Super Hulks and Class 1 Drillers. Destroy them, and pick up the two shield powerups.

The corridor will make it difficult to detect the two Fusion Hulks. You will have to destroy them.

The reactor room is guarded by two Super Hulks and a Medium Hulk. The Super Hulks are located in niches across from the reactor. You will have to destroy both of them to be able to comfortably destroy the reactor.

Once you have blown the reactor, return to Shaft Junction and head for the exit in the lower area.
