Parasite

Parasites are a demonic creature from Hell. Very little is known about them.

Several parasites can be seen in tubes in Lazarus Labs.

Larger parasites can be seen entering the Hell Guards.

Behind the scenes

 * They maybe connected to the little known 'gremlin'/'Abaddon pilot' race.
 * These appear to be younger speciment of the 'parasite' that control the hell guards
 * These can be ripped out of a hell guard and 'killed' via a Glory Kill.
