Level 3 warning

A Level 3 warning is a security protocol alluded to in Metroid: Other M. The Bottle Ship P.A. Announcer states that it is in effect in Sector 1 / Biosphere, and advises the inhabitants of the BOTTLE SHIP to avoid traveling alone, remain armed, and stay alert to their surroundings at all times. Whether or not this has anything to do with MB is unknown.
It is only in effect in the Biosphere, as a higher Level 4 warning is in effect in the Cryosphere and Pyrosphere.
