Sleep suppressor

Sleep suppressor

A scavenged archotech shard mounted in an electrical control frame. The device creates a psychic pulsation in the local area which alters the brain chemistry of those nearby, halting the buildup of fatigue toxins and removing the need for sleep. However, it also irritates anyone nearby.

The sleep suppressor is a building added by the Anomaly DLC that gives nearby colonists the sleep suppression hediff, but also gives them a mood debuff.


Sleep suppressors can be constructed once the sleep suppressor research project has been completed. Note that this research requires dark study to unlock. Each requires Shard 1 Shard, Bioferrite 100 Bioferrite, Steel 25 Steel and 6,000 ticks (1.67 mins) of work modified by the construction speed of the builder.


Colonists within an 8 tile radius of the sleep suppressor will gain a −6 mood debuff, and slowly build Sleep Suppression while they remain within the radius.

Sleep Suppression progresses in several stages:

  • Very Mild (0% - 9.9%): No effect
  • Mild (10% - 29.9%): Sleep Fall Rate x50%
  • Moderate (30% - 65.9%) Sleep Fall Rate x15%
  • Extreme (66% - 100%) Sleep Fall Rate x0%

When outside of the radius, pawns lose progression on sleep suppression very quickly.


The Sleep Suppressor is very effective when placed within your workshop and laboratory, where pawns are likely to sit in place for long periods of time needed to build up the sleep suppression to the maximum. This effectively allows pawns to craft or research for longer periods of time before they need to stop to satisfy other needs, like hunger or recreation. It can be combined with a Frenzy inducer to make pawn work even more efficient, though at the cost of additional mood debuffs.

In theory, one could also built in the rec room and dining room, to keep those pawns awake close to indefinitely, though these rooms are much less frequently idled in by an efficient colony, making the extra costs to have additional units in these areas much less favourable.

Like other similar buildings such as the Frenzy inducer, these should be turned off when moods are low in the colony. A happy pawn is more efficient than a sleepless pawn in the long run, after all.
