Sentry Missile

Sentry Missiles are obstacles seen in Metroid Prime: Federation Force on Talvania. They often spawn quickly, and launch themselves at intruders. However, given their slow and telegraphic startup and weak shielding, the Missiles can be easily destroyed and usually spawn in threes. They are encountered during M03: Smokestack in the power station. In the first corridors, they seemingly spawn from acid. The Generator encountered later in the power station spawns these Missiles when it is venting excess gas, as a defense mechanism.
