The UAC research complex established on Deimos, moon of Mars, similar in design and purpose to the UAC Phobos Base. The base complex can be seen nested in a major crater, most likely Swift or Voltaire.
The UAC built sections of the moonbase include
- Deimos Anomaly, location of an interdimensional Gateway
- Containment Area, a large warehouse facility
- Deimos Lab, central scientific laboratory
- Command Center, primary operations center
- "Halls of the Damned", corrupted by demonic forces, former purpose unknown
- "Spawning Vats", corrupted by demonic forces, former purpose unknown
Another two locations exist inside the same crater of the lost moon, but appear to be fully of Hellish origin.
