A Construct is a type of synthetic that is nearly completely organic compared to synthetics. Skeleton wise, it can be assumed its similar to most androids but the outer flesh, muscles and possibly the brain seem to be human-like in quality as its vunerable to the Chemical A0-3959X.91 – 15 accelerant, which alters their physical appearance and behavior as well.

Notable Constructs

  • Elden: Elden is the only Construct introduced so far and switches between a supporting character and an antagonist as he continues to "evolve", eventually he merges with 'the mountain' which is revealed to be a living organism that has over-taken the wreckage of Prometheus and possibly the Juggernaut.


  • Like the film, the Prometheus series introduced an android more advanced than others of the current or future date, David was more advanced than Ash, and was able to still function without a head, whereas Ash had to be re-activated, and Elden is more organic and life-like than Bishop.
