This level is extremely straightforward. You will meet Class 1 Drillers, cloaked Class 1 Drillers, Class 1 Heavy Drillers, Super Hulks, Defense Robots, and sometimes a drone or a platform robot. Wise navigation of this level is the key to getting out of here with minimal problems. 

• There is a shaft indicated in the opening room. It contains a shield powerup. UNDER NO CIRCOMSTANCES SHOULD YOU GO DOWN THE SHAFT. If you do, the robot generators in the robot generator room will activate, releasing Class 1 Drillers and cloaked Class 1 Drillers. They will not stop...
• If you die in this level, be aware that upon heading out from the entry point you will be hit by vulcan cannons. This cannot be stopped until you destroy the cloaked Class 1 Driller in the corridor leading to the reactor room.

The opening room is guarded by three Super Hulks.  Right outside this room near the entry point in a corridor branching to the right are several Spider Processing Robots and Class 1 Drones.  Destroy them all.

Next, you will need to take out the Super Hulks.  To do this, return to the entry point corridor and enter the opening room by the door ahead.  The three Super Hulks will be at the other doors.  Quickly grab the invulnerability in the middle and destroy the three Super Hulks as quickly as possible.  This is essential as you will have to go through this room to escape the mine.

Once you have done so, go out via the door indicated and head for the blue key via the shaft.

This area is the place where you can grab all three keys, since they are within the same vicinity.

Upon heading down the shaft, you will see a blue door. Once you emerge from the shaft, you will encounter two Class 1 Heavy Drillers. You will have to destroy them before attempting to grab the blue key. It is possible to fire a smart missile while in the shaft, but the depression in the floor renders the plasma trackers useless.

Once you have done so, enter the back area that contains the energy generator. Once you cross the generator, you will come under immediate attack by two Super Hulks.  It is suggested that you take out the Super Hulk in the niche with the secret room first, rest a while in the secret room, then take out the other Super Hulk. Once you destroy both of them, go on your merry way and grab the blue key.

This area contains the yellow key and the hostages. This area is guarded by Defense Robots scattered around the area.

Once you go down the shaft, you will come under immediate attack by two Defense Drones. Since the floor of the room is lava, you may fire under them and destroy them. Go through the level and eliminate all the Defense Robots, then grab the yellow key at the position on the map.

Once you have grabbed the key, you will have to return to the blue key room to get to the yellow door.

The hostages are located behind a secret door indicated on the map. It is suggested that you do not rescue the hostages until you have defeated all the enemies inside the reactor room. Once you are ready to grab the hostages, grab them and pick up the extra life located in the secret niche indicated.

Many thanks to Fred Scheifele([email protected]),Prion([email protected]) and Joerg Reibert([email protected]) for their advice. If my way was followed, a loss of lives would result.

The red key is located in the bottom of a shaft circled by a helical tunnel. This key is guarded by four Class 1 Drillers ,two Super Hulks, and several Class 1 Drones with mine capabilities.

As may be seen on the map, the shaft is connected to the helical tunnel by niches with grates. All the Class 1 Driilers in this room will be in these grates(one per grate). The drones hover around the helical tunnel.

Switch to your lasers and homing missiles(if you have them) and start up the tunnel. Stop when you come to the grate(it should be to your left). Use your weapons to destroy any drones and mines nearby.

The next step is extremely crucial. Face the front of your ship towards the left side of the tunnel. Then slide right and when you have the driller in your sights, destroy it with your lasers. Continue up the helical tunnel, repeating the previous steps for every grate.

Once you near the top of the shaft, switch to your plasma cannon(if you have one) and take out the Super Hulks lurking on the top of the shaft.

If the steps were followed, you should have a clear path to the key at the bottom of the shaft.

There are four secret rooms in this area:

• In the helical tunnel near the top of the shaft which contains a smart missile,
• In the shaft which contains a fusion cannon guarded by two Class 1 Heavy Drillers,
• In the shaft which contains a smart missile,
• In one of the niches which contains a pack of homing missiles.

This is the room which, if you were greedy and you picked up the shield powerup in the opening room, would punish you.

This room is extremely dim. Open the door to the room and immediately fire a homing missile. This will blow up a Class 1 Driller. Circle the room and blow up the rest of the drillers.

If you were greedy and the robot generators in the room activated, you will experience a major roadblock. You will have to face cloaked drillers(which can be almost impossible to catch).

Go down the corridor indicated, destroy the cloaked Class 1 Driller located there, and head for the reactor.

This reactor room is never fun. Even though the reactor room is very spacious, the enemies will drive you crazy. This floating(!) reactor is guarded by three Class 1 Drillers and four Green Platform Robots.

Three of the green platform robots are congregated in a corner, the Class 1 Drillers are located in another corner, and there is a lone platform robot located above the reactor. Switch to the weapon that you are most comfortable destroying these robots and destroy them all.

Firing a mega missile is not advisable here. The room is too small for you to avoid the blast radius of a mega missile.

Once you destroy all the enemies, rescue the hostages in the yellow key room. Then do your worst on the reactor.

Upon destroying the reactor, head out the way you came, up the corridor that was forbidden, and head for the exit straigh ahead of you.
