ROBOT: The Assaultron is a robot. They are immune to the effects of starvation, thirst, and suffocation. They are also immune to Poison and Radiation damage. However, machines cannot use food and drink or other consumables, they do not heal naturally, and the Medicine skill cannot be used to heal them: damage to them must be repaired (p.34).
IMMUNE TO POISON: The Assaultron reduces all Poison damage suffered to 0 and cannot suffer any damage or effects from poison.
IMMUNE TO RADIATION: The Assaultron reduces all Radiation damage suffered to 0 and cannot suffer any damage or effects from radiation.
IMMUNE TO DISEASE: The Assaultron is immune to the effects of all diseases, and they will never suffer the symptoms of any disease.
KEEN SENSES: One or more of the Assaultron's senses are especially keen; they can attempt to detect creatures or objects which characters normally cannot, and they reduce the difficulty of all other PER tests by 1 (to a minimum of 0).
SELF-DESTRUCT: If the Assaultron has both its arms or legs injured, or it has been reduced to half or fewer of its maximum HP, it will move towards the nearest enemy and use its major action to self-destruct. This self-destruct is an attack centered upon itself and destroys the Assaultron after it attempts this attack.
NIGHT VISION: The Assaultron can see in complete darkness. It ignores all difficulty increases caused by dim light or darkness, and they may attempt skill tests that would normally be impossible in darkness
