Doom 3 locker codes

Security codes are used to open storage lockers and other sealed areas in Doom 3. They are almost always obtained from PDAs on the same level, via emails or audio log entries. Many of the heavy weapons and large powerups are locked up, so the more codes are found, the better equipped the marine becomes.
