The protozoan is an inoffensive entity seen on Xen.

Overview[edit]

The Protozoan appears as a bluish, transparent rock-like entity orbiting above the ground, with a smaller reddish rock-like shape inside, also transparent and turning on itself. It has no AI, cannot be destroyed and does not react to the player's or any NPC's presence.

It is first seen in Half-Life for a few seconds during the Resonance Cascade, orbiting behind two Bullsquids drinking from a Healing Pool. It is also seen in the same map in Opposing Force (reached several times with the Displacer Cannon) as well as Decay, at the very start of the bonus chapter, Xen Attacks.

Behind the scenes[edit]

The "protozoan" (Gr. "prôtos", "first" + "zôon", "animal"), also named "protozoon", actually exists. It covers any of a large group of single-celled, usually microscopic, eukaryotic protist organisms commonly living in water, such as amoebas, ciliates, flagellates, and sporozoans.[1] Protozoa can be plants, fungi or animals. Thus the Protozoan can be considered as an extremely enlarged protozoan that does not live underwater.

The Protozoan uses a single animation, named orbit. The model name, protozoa, is actually the plural form. Elsewhere in the Half-Life files, an unused stick-like model named stick uses the same texture as well as a single animation, also named orbit. Its relation to the Protozoan is unknown.
