The Clustonbury Theatre is a location in Red Grave City. The show "Rise and Fall of Spencer" was scheduled to be performed between June - July. The main cast would be composed of Mabel Babcock, Walter Mitchell and Ralph Hylands, with Scott Danels working behind the music, Farren Richardson as the conductor and Rachel Broderck as the choreographer.
When Qliphoth roots started to appear in May in Red Grave City, it took the entire theater with it which destroyed it almost completely. During Mission 07: United Front, Nero and V ended up at the ruins of the theater where they faced a Proto Angelo and Scudo Angelos. During the battle, the stage area of the theater got disconnected off of the auditorium and it started sliding off towards the main root of the Qliphoth.
- The stage area is used again during Secret Mission 08.
- "Rise and Fall of Spencer" may be a reference to Oswell E. Spencer from the Resident Evil series. Spencer was one of the characters who was supposed to appear or be mentioned in one of the cancelled versions of Resident Evil 4, which ended up turning into Devil May Cry.
