VS. Hive Totem

Vs Hive Totem is, as the name implies, the main boss theme for the Hive Totem, and to a lesser extent the Incinerator Drone. The song opens up with a low choir chanting three times, and then the choir chanting repeatedly in multiple pitches in the background while beats are heard.

The song may have been planned for the prototype game for Metroid Prime, Action Adventure, in particular with the BloodMonkey character, as the in-game files for the portion where Samus fights against the Incinerator Drone lists the theme used against it as "rui_monkeylower"
