The Hive Mind appears similar to the other Necromorphs encountered in the game, however unlike many of the individual Necromorphs, the Hive Mind is not re-animated human flesh. One such Hive Mind, referred to by the researchers of Tau Volantis as a "Nexus", serves as a boss fight midway through the game. The planet Tau Volantis, as seen in the sequel Dead Space 3, was the home of an alien civilization that was in the final stages of being overwhelmed by a Necromorph infestation when its destruction came at one point, a valley can be seen containing several fully-formed, albeit frozen solid, Hive Minds.

Since it is ultimately the source of all Necromorphs, it serves as the final boss in the game. The Red Marker had some sort of power over the Hive Mind, keeping it sealed under Aegis 7 until it was discovered during the mining operations just prior to Dead Space. Either way, the secret government agency doing the tests deemed the creature too dangerous, and abandoned the project. It is not entirely clear if it was created on purpose through the tests with the Red Marker, or if it was an accidental outcome of other testing going on.

The Hive Mind was created on Aegis 7 almost 200 years prior to the events of Dead Space, as a byproduct of the Red Marker.
