Alien Robots are small robots created by the Precursor Race. They are found roaming within the Alien Thermal Plant and the Primary Containment Facility.

Their main function is to repair and uphold Alien Bases and as such are equipped with two welding tools. They are also programmed to defend Alien Bases from intruding life forms, and will use the aforementioned tools as weapons if the need arises. Despite being created by the Precursor Race, these robots are simple, even in comparison to current human technology.


The Robot is similar in size and shape to the Cave Crawler, but coloured in the same way as most Precursor Technology, being predominantly dark grey with green luminescence.

The 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.


Upon sighting the Player, the robots become aggressive. Thrusting their two welding tools towards the player, dealing 3% damage per hit. They spark when they take damage and explode when destroyed.

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

Data Bank Entry

Precursor Droid-0

This device does not match any known human technology, although its design is relatively simple. Its only observed behavior has been attacking local lifeforms in a radius around the ancient alien structures.

  • Features few moving parts
  • Carries a rechargeable, ion-based power reserve
  • Reliable and energy efficient

Modeling the age and purpose of the device is difficult. Its relative harmlessness is at odds with the advanced technology apparently available to its designers.

Assessment: Further research required



  • 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.
