After the protagonist first infiltrates the Shrouded Bunker to destroy the clan's bomb caches and then completes the quest "Feltrite Crater", "A Proposition" mission will be available from the Job Board in Wellspring which is to find Phallinx in the Hagar Settlement. He then will offer the mission "RC Prototype", in which the protagonist must infiltrate the bunker once again to acquire an advanced RC Bomb Car prototype. He will reward the protagonist with the Advanced RC Bomb Car schematic.
- In the Wasteland Legends co-op mission "Life in Prison", one of the two playable character models is Phallinx's.
- Some of Phallinx's dialog refer to "strange noises" coming from below the settlement. This is a reference to RAGE: The Scorchers, and was the first indication of the DLC's existence.
