Alien Robots are small robots created by the Architects. They are found roaming within Sanctuary Zero and the Crystal Caves Cache.

Their main function is to repair and uphold Architect Bases and thus are equipped with two welding tools, which can deal small amounts of damage. They are also programmed to defend Alien Bases from intruding life forms, and will use the aforementioned tools as weapons if the need arises.

Appearance

The Alien Robot is similar in size and shape to the Cave Crawler, but colored in the same way as most Architect technology, being predominantly dark grey with green luminescence.

The Alien Robot has an octagonal body with a small head on the front and a larger, rectangular object on the back. It has four legs split into three segments each. Two green tipped stalks used as repair tools protrude from its back. Decorative patterns are carved into most parts of the Alien Robot.

Behavior

Upon seeing the Player, the robots become aggressive, attacking by thrusting their two welding tools towards the player which deal 3 damage per hit. They spark when they take damage and explode when destroyed.

Alien Robots are also capable of climbing the Prawn Suit, this however, will not damage the vehicle.

Data Bank Entry

Alien Robot

Precursor Droid

This device is of alien origin, although its design is relatively simple.

  1. Purpose: Its low threat level is at odds with the advanced technology apparently available to its designers, suggesting it was intended more to patrol alien facilities and repair damaged infrastructure than to deter invaders.

  2. Design: Despite its simple design, this construction is quite elegant in its minimalism. Four electro-magnetic legs allow it to traverse floors, walls and ceilings with reasonable speed, and appear to be replaceable. Internally there are few moving parts, rendering this construct energy efficient, and resistant to wear over time. A rechargeable, ion-based power reserve ensures it continues to operate.

Trivia

The Alien Robot was previously called the Alien Drone and prior to that, Precursor Droid.

The looks for the Alien Robot were inspired by Cave Crawlers, and in early development they shared the same set of animations, currently they use a set of animations similar to the Cave Crawler, but augmented to look more mechanical.
