Restricted Lab

Welcome to the Restricted Lab, a critical area for advancing your mission. This section will guide you through the perilous path, ensuring you acquire all necessary upgrades and navigate the challenges ahead.

Initial Entry and Navigation

Upon entering the Restricted Lab, you'll find yourself in a long, vertical shaft. Your immediate goal is to descend.

  • Head left from the entrance to find a small chamber. Here, you'll encounter a new type of enemy, the Fune, which can be dispatched with a few shots from your Arm Cannon.
  • Continue descending the main shaft. Be wary of the Mute enemies that cling to walls; a well-aimed missile can take them out quickly.
  • At the bottom of the shaft, you'll find a door to your right. This leads to a save room. It's highly recommended to save your progress here, as the upcoming sections can be challenging.

Acquiring the Diffusion Missile

After saving, return to the main shaft and proceed left. You'll enter a series of interconnected rooms.

  • Navigate through the narrow corridors, dealing with any remaining Fune.
  • You'll eventually reach a large chamber with a central platform. On this platform, you'll find the Diffusion Missile upgrade. This powerful upgrade allows your missiles to explode with a wider radius, affecting multiple enemies or breaking multiple blocks simultaneously.
  • Strategy: To acquire the Diffusion Missile, you may need to clear the room of enemies first. Use your regular missiles to clear any blockages leading to the platform.

Proceeding to the Security Room

With the Diffusion Missile in hand, your next objective is to reach the Security Room.

  • From the Diffusion Missile acquisition point, head back to the right, through the corridors you just traversed.
  • You'll encounter a section with several Zebesian enemies. Use your newly acquired Diffusion Missiles to clear them out efficiently.
  • Look for a door on the upper-right side of this area. This leads to a small, vertical shaft.
  • Ascend this shaft, being mindful of any flying enemies. At the top, you'll find another door.
  • This door leads directly into the Security Room.

Security Room Encounter and Data Download

The Security Room is a crucial point in the Restricted Lab.

  • Upon entering, you'll receive a communication from the computer. It will inform you about a critical system malfunction and the need to download data.
  • Warning: The SA-X will likely make an appearance in this area. While you cannot defeat it at this stage, you must avoid its attacks. Use your Speed Booster to quickly escape if it spots you.
  • Your goal is to reach the central console in the Security Room. Interact with it to initiate the data download.
  • Once the data download is complete, the path forward will open. A door on the lower-left side of the Security Room will unlock.

Exiting the Restricted Lab

With the data acquired, it's time to leave the Restricted Lab.

  • Head through the newly unlocked door on the lower-left of the Security Room.
  • You'll find yourself in a short corridor leading to an elevator.
  • Take the elevator down to exit the Restricted Lab and proceed to the next sector.
