The Compound is a major location added by the Underrail: Heavy Duty expansion. It can be accessed by accepting Trip to North Underrail quest given by Buck Nimble in Upper Underrail.

Description

The Compound, also known as Transregional Joint Research Compound or Oneiros Compound is an old Biocorp's facility located in the Dark Territory between South Upper Underrail and North Upper Underrail. Abandoned for centuries, it is patrolled to this day by Exosoldiers - an army of identical telepathic clones.

The location is regularly patrolled by the exosoldier squads which will attack the player on sight. Each patrol consists of randomly chosen exosoldiers accompanied by a Technomedic, random tactical support bot and sometimes also an Intercessor. The number of patrols is finite, however if player kills all normal exosoldiers, then the patrols will be replaced with squads of elite psionic commandos - Psychophracts. Exosoldiers sometimes also create barricades in the Compound, blocking the way and making moving around the facility more difficult.
