Timed Security Chest

The Timed Chest is a Chest with a counter on it. It can only be found in one of the two Third Stages, Rallypoint Delta. In order to open it, the player needs to reach it within 10 minutes. Upon opening, the "[REDACTED]" achievement is unlocked along with the Preon Accumulator.

There will be a small trail of red-light standing lamps that lead to the chest. Usually accompanied by a couple pairs and a few singular lamps that lead in between them. [Verify]

 * on top of the hill next to a radar tower
