Power-Locked Rooms are rooms that are electronically locked by metal doors, which can only be unlocked by fuses.
There are two variations of power-locked rooms, the lower deck variation, and the upper deck variation.
- The lower deck variation is a large metal room which is divided by a metal grate. Four static security monitors sit on a set of drawers and cupboards.
- The upper deck variation is a large metal room that is divided by wooden poles. A set of 6 drawers stand in front of the door, and four static security monitors rest on a desk, in the corner. Two lockers are placed at the other corner, next to a desk with a lamp.
- The objective of the achievement "Now Think About What You've Done" is to lock a monster in one of these rooms. Note that locking a monster in one of these rooms is only temporary, as each one has the ability to get out in some way.
- These rooms always contain a valuable item, such as a Backpack, Chain Spool, Flare Gun, Flashlight, Helicopter Keys, Pump, Radio, or Sub Battery. You can also find Notes inside them.
