In the "Revelations" DLC, the diary of a soldier's corpse can be found. The name of the soldier is "Angry Sir Rolfe", who is named after James Rolfe, known as "The Angry Video Game Nerd". The diary contains reference to Rolfe's first video game review of Castlevania II: Simon's Quest.
The character Victor Belmont was originally planned to appear in the cancelled Dreamcast game "Castlevania: Resurrection". Lords of Shadow 2 is the first Castlevania game to be released that Victor appears in.
