The Infested Voiasensos are unfortunate Voiasensos which were taken as hosts for parasitic Xrondo eggs, and upon its hatching they are left in a zombified state; technically dead although still barely coherent. What little of their mind remains must watch in horror as the Xrondo rips its former allies apart.
"Like many other species, Voiasensos have been subject to infestation by the eggs of the Xrondos, a race of xenomorphs who use other species' bodies to protect themselves. The hosts die in the process of takeover, but are left in a zombified state."
