The Psi-Reaver represents a final stage in the Annelid’s parasitic life cycle. When an Annelid Hybrid has mutated enough, its physical body is absorbed by The Many’s biomass. The remains from this process form a structure of nerves and bone, which resemble a brain and spinal column. These structures project powerful floating psionic forms.
Psi-Reavers are psychic beings and the most advanced and metabolically expensive forms for The Many to produce. Psi-Reavers float through the air, mostly keeping their distance from the player, as the rely on ranged psychic attacks. Killing only the Psi-Reaver’s floating “body” is a temporary measure - when destroyed, this projection will reappear after 30 seconds. In order to permanently kill a Psi-Reaver, the player must locate and destroy its vulnerable brain stem.
The Psi-Reaver projection lacks any humanoid features whatsoever. They are squid-like in appearance, with four tentacle-like appendages dangling from their flesh-tone body. As psychic beings, they are capable of flotation, which is their primary means of movement. The Psi-Reaver’s “brain” is physically separate from the “body” - the “body” is a psychic projection of the Psi-Reaver’s will. The brain is defenseless and cannot move. Therefore, it's often found in alcoves or other concealed areas.
A more powerful variety, the Greater Psi-Reaver, also exists.
The first Psi-Reaver in System Shock 2, Anatoly Korenchkin, can be found on the Von Braun’s bridge. Several more can be found on board the Rickenbacker and inside The Many. Unlike most other enemies, Psi Reavers do not respawn or appear randomly.
The Psi Reaver is a bit different from other enemies. Rather than attacking it directly, you should search for its brain instead, which usually will be hidden nearby. The Psi Reaver itself is big, tough and does a decent amount of damage, so it's generally not worth attacking directly. Once the Brain has been destroyed, the Reaver itself can be killed for good.
How dangerous they are depends on how well they have hidden their brain structures. Psi-Reaver Organs can be researched with a small quantity of Radium and Technetium for a 25% damage bonus dealt to both their projections and brain structures.
