Things You'll Need
Instructions
Security Doors
Talk to Adam, the space station's supercomputer, in the first Navigation Room when you begin the game. This will unlock the station's gray doors. To open these doors, just shoot the door with your normal beam weapon.
Disengage the security lock in the Security Room found in Sector 2. This will disable Level 1 Security and will allow you to open up any blue doors found throughout the station. Like the gray doors, these can be opened with a normal beam shot once the lock has been released.
Travel to Sector 3, find the Security Room, and disable the Level 2 Security locks. This will unlock any green doors you come across throughout the game. These can also be opened with a normal beam shot.
Locate the Security Room in Sector 5 and disengage the lock to shut down Level 3 Security and open any yellow doors found in the station. Like the rest, these can be opened with a beam cannon shot.
Run over to Sector 4, locate the Security Room, and remove the Level 4 Security lock to open up the station's red doors. The red doors are the last of the Security Doors, and can be opened with a beam shot.
X Barriers
Shoot green X Barriers with three regular missiles to destroy them. The X Barriers are organic obstacles that each require different weapons to get past them.
Shoot purple X Barriers with three Super Missiles to gain access to the areas they are blocking.
Crouch down into the Morph Ball position and drop a Super Bomb to blow up the large yellow X Barriers hindering the completion of your mission.
