SODUS

The Single-Operation Direction and Utility System (SODUS) is an artificial intelligence developed by the Enclave. It is located in the Enclave research facility in the Forest region of Appalachia in 2103.

Background
An AI similar to that of MODUS, SODUS is the artificial intelligence formerly responsible for overseeing all operations in the Enclave research facility, created to assist visitors with extreme kindness and hospitality, with a variety of secondary functions, such as answering questions. Although despised for its multiple-hour queues for simple tasks, such as three-hour waits for scout decontamination, it collected and recorded approximately fifteen years of data through the facility's history, while also being in charge of access, food, air and water supplies, and other facilities. Due to employee interference, the facility was reduced to having recycled food paste for six years, similar to that of the Nutritional Alternative Paste Program, as well as a glitch causing the loss of 85% of the potable water. SODUS also began utilizing terminal communications to selectively shut off and restrict access to employees, prompting them to begin using paper notes. By the time of the Scorched Plague, SODUS detected the pathogen through its sensors, having recently been upgraded with the same functionalities as MODUS, recalled any outside scouts, and purged the facilities data. From there, it shut off the air filtration system, and began pumping in air from the outside, intending to kill all those inside. Between this time, MODUS determined that Site J no longer had any use, and cut all communications with it, sealing it off for many years. By the time the vault dwellers reach the facility, SODUS has nearly 152,000 tasks completed, with a wait time of over 14,320 hours for normal entrants (approximately 6,599 for Enclave generals.)

Appearances
SODUS appears only in Fallout 76, introduced in the Steel Dawn update.
