Security Drone

Silent mechanical sentinels guarding the wreckage with lethal precision against intruders.

Security Drones are automated defense constructs deployed by the Aurora class vessel following its catastrophic crash on Planet 4546B. These mechanical sentinels patrol restricted zones around the wreckage, programmed to neutralize any unauthorized biological presence detected within their perimeter. They represent one of the few remnants of human technology still actively functioning in the alien ocean depths.

Lore & Background

Originally designed to protect sensitive cargo and crew quarters, these units remained operational long after the ship's main power failed elsewhere. Their persistence highlights the durability of radiation-resistant tech found on the vessel, capable of surviving the impact and subsequent flooding.

The tragedy lies in their inability to distinguish between a threat and a survivor seeking refuge. They operate on rigid logic loops that classify any diver near the hull as an intruder. This automated hostility adds a layer of danger to exploring the very ship that brought humanity to this world, turning safety into a trap.

In Their Own Story

The hum precedes the sight. A red light flickers in the dark water near the hull breach. One hovers, then two. Lasers charge with a sharp whine. You dive deeper, but they follow. The sound of shattering metal echoes as you escape into the reef, leaving the silent guardians to their eternal watch.

Reader's Guide

Security Drones serve a singular purpose: protect the Aurora's integrity by eliminating intruders. They operate without human oversight, relying on motion sensors and proximity triggers activated upon crash impact. Their technology represents advanced automation capable of functioning in high-pressure underwater environments without external maintenance. Unlike biological fauna, they do not hunt for food but strictly enforce perimeter protocols.

Within the hierarchy of the planet's threats, they sit between minor fauna and large predators due to their coordinated swarming behavior. They pose a significant risk to early-game explorers who lack proper armor or weaponry. Their presence indicates proximity to high-value wreckage zones where resources are plentiful but danger is heightened. Ultimately, they represent humanity's own defenses turned against its survivors, a grim reminder of the isolation and failure that befell the ship.

Relationship with the ecosystem is purely antagonistic; they disrupt natural habitats through noise and aggression. They do not reproduce or evolve, relying solely on pre-programmed logic. For players, understanding their patrol patterns is essential for safe navigation near the crash site.
