This secret level is the easiest of the three. As the name implies, this is a supply depot, and you will be able to get out alive with a full armament if you are extremely careful and skillful in the rescue of the hostages. You will only meet Super Hulks and Class 1 Drillers if you are careful, but you will meet much more if you are not careful....

Warnings: 

• The four doors labeled "1." MUST NOT be opened or entered from the outside(meaning from the outer area to the inner area). If you do so, you will activate the robot generators, which will generate cloaked robots.
• The four doors labeled "2." cannot be opened on the outside.
• Make sure that your joystick is calibrated correctly. This will help tremendously in rescuing hostages.

1. Go through the outer area and pick up a cloaking device. There should be one right in front of the entrance. Go around the outer area and using homing missiles, smart missiles, and lasers, destroy all Class 1 Drillers.
2. Enter the duct and pick up another cloaking device. Go through the holes marked "3." on the map and pick up the red key, the extra life, and blow up as many Super Hulks in the inner area as you can. If you cannot destroy them all by the time the cloak runs out, go back for another cloak and enter through the duct again, but leave at least ONE cloaking device alone(preferably the one in front of the red door).
3. Next, rescue the hostages. Using your flares, open the doors marked "2." from the inside through the grating. Once you hear the door open, go out through the doors labeled "1." and go into the door you just opened. This must be done extremely quickly. Repeat for all unrescued hostages. Each time you rescue a hostage, you may collect some weaponry.
4. After all the hostages are rescued, pick up the last cloaking device and open the red door.Once you have done so, use your cloaking device and the invulnerability inside the reactor room and destroy the three Super Hulks guarding the reactor.
5. Destroy the reactor.
6. Head for the secret room inside the duct. The door should open, revealing three Supervisory Robots. Use your fusion cannon and destroy them all. One will release mega missiles, another an extra life, and another Class 1 Drillers. Fire your fusion cannon once more to destroy the drillers, and head for the exit.
