Rumbler is a Hybrid that has mutated/matured further.

Rumblers first start showing up late on the Recreation deck, and are seen throughout the rest of the game. If you have Research skill and some Molybdenum, you can research a Rumbler Organ to get a damage bonus against them.

Attributes: High Hit Points, high damage, medium (?) attack speed, high movement speed.

Biology Edit

This organism marks a further evolution of the first-stage Annelid Hybrid. Discernible human elements are minimal above the DNA level. In this stage, dense musculature grows all over the body, and the body undergoes massive development in all physical attributes, becoming a hulking humanoid monstrosity. However, the brain stem atrophies, and all control is provided by the cells of the body. The resulting creature is essentially a fast, tough, aggressive biological killing machine.

Research performed on a Rumbler organ suggests that the body is designed to protect the hyper-developed, but unconnected brain for a further part of the life cycle.


The Rumbler is much faster than a creature of its bulk has any right to be. Try and find a sniping position where it can't reach you, or it will rip you apart within seconds. Since its form is mostly Annelid, it is particularly vulnerable to Incendiary damage, and reistant to Energy. Be prepared to use a lot of ammunition to take one down.

Rumblers are also vulnerable to Psionic Hypnogenesis and Imposed Neural Restructuring, as well as the effects of theStasis Field Generator.

Tactics Edit

  • Avoid combat if possible.
  • Listen, you'll hear one before you see it.
  • Engage at long to medium range.
  • Use anti-personnel ammunition.
  • Circle and strafe the creature if in melee range.
  • Know your surroundings.
