Just when you thought the levels could not get any harder, here comes this level with only Class 1 Drillers, Class 1 Super Drillers, and Super Hulks, the three toughest enemies in the game that you have encountered so far...with some Medium Hulks scattered around the level.

However, note that there are several cloaking devices, invulnerabilities, and other useful items. Use them well, and you will be able to get out of the level with the hostages. 

• Be aware that you are fighting a level with only Super Hulks, Class 1 Drillers, and Class 1 Heavy Drillers. This means that you will not be able to attack them face to face without taking some damage.

Note: This map is simplified. Not all features of the room are shown.

The first thing you should do at the beginning of the level is to fire your plasma cannon ahead. Let it open the door in front of you and the door after that. You will hit a Super Hulk and maybe several other Class 1 Heavy Drillers. Fire some homing missiles to make the destruction complete.

The opening room is guarded by three Super Hulks and a great number of drillers. You will have to first destroy the Super Hulks first. They are located by the red door. If you have smart missiles, use them. Use your smart missiles at long range and then use your lasers at close range. This will get rid of the Super Hulks. A Class 1 Driller may lurk around and attempt to hit you from behind; just use a homing missile to destroy it.

The features of this room will be discussed:

• (Not shown on map) Underneath the door from which you entered the room is a passageway. It contains a energy generator, vulcan ammo, and a laser powerup. It is guarded by two Class 1 Drillers. In this area you can see the tantalizing yellow key, but you cannot grab it...This area should be visited since destroying the drillers will make the yellow key easier to get.
• (Not shown on map) In the pillar at the very bottom across from the red door is a door. Do not open it...there will be at least three Class 1 Drillers attacking you...
• (Not shown on map) In the pillar on the opposite side from the entry point, is a depression. This depression is a secret door.  Open it and you will enter a room with several Medium Hulks.  Destroy them all and you will have a missile cache at your disposal.
• There is a shield powerup located in a niche across from the robot generator.  DO NOT PICK UP THIS POWERUP.  If you do, the robot generator will activate, forming Class 1 Drillers and Class 1 Heavy Drillers.
• There is a door located to the left and up of the robot generator. This room leads to another small weapons cache guarded by a Medium Hulk and two Class 1 Drillers.
• The door to the blue key room is located in the corner indicated in the map.
• The door the rest of the level is located on the pillar right across from the room from which you entered.

Once you enter this room, you will come under immediate attack by several Class 1 Drillers.  Destroy them with homing missiles.

There is a Class 1 Heavy Driller in lay to ambush you in the side corridors.  Before grabbing the key, destroy it as quickly as possible.

Once you have grabbed the key, go into the side corridor at the point indicated and open the secret door.  Grab the cloaking device, and quickly head for the door that leads to the rest of the level. Destroy the two Class 1 Drillers located there with homing missiles and destroy the Super Hulk using any weapon desired. Then, continue on with the level.

Once you enter this room, you will come under immediate attack by two Class 1 Heavy Drillers. You will have to circle the room(you will have barely enough space to do so) and destroy both drillers. Then, head down the corridor to your right and go down the shaft. Destroy the Super Hulk lurking down there.

You should then have a clear path to the key, since you destroyed the Class 1 Drillers in the adjoining corridor.

If you want to rescue the hostages, return to the room which you came in from and open the door indicated.  Grab the invulnerability and open the secret door behind it. Destroy the two Super Hulks guarding the hostage doors, and rescue the hostages.

You will have to return to the opening room to grab the red key.

Once you enter the antechamber leading the the yellow door, you will come under immediate attack again by two Class 1 Heavy Drillers.  Again, destroy them by circling the room and destroy any in the two left side passages, if necessary. (The left side passages are useless.)

Next, grab the invulnerability located in the right side passage behind the secret door. Once you have done so, immediately enter the yellow door, hurry to your left and enter the door.  Destroy the drillers in the next room with homing missiles, then go down the hole to the lower chamber.  Destroy the two Super Hulks there, then open the door and grab the key.  You should be able to do this before the invulnerability runs out.

Once you have grabbed the key, you may keep going straight and access a series of doors to grab a mega missile. You may also head for the secret door near the hole and grab a fusion cannon and shield powerup.

You will have to return to the opening room to access the reactor.

The reactor room is guarded by two Class 1 Heavy Drillers and three Super Hulks.  Change to your smart missiles and the weapon that is most comfortable for destroying both types of enemies before entering the room.

At the lower level, the Class 1 Heavy Drillers are waiting in ambush in the side corridors. The best way to destroy them in this ambush position is to choose one side, force your way behind the driller, destroy it, and destroy the other driller in any fashion desired.

Once you have destroyed the drillers, grab the shield and energy powerup and stay there.  Aim at the upper wall, and fire any number of smart missiles. WARNING: SAVE ENOUGH FOR LEVEL 13. This will weaken the Super Hulks around the reactor. Then, turn around, go backwards, and slide up. Destroy the three Super Hulks as quickly as possible, then blow the reactor.

The exit is located behind the reactor.
