DevelopmentThis game was in development hell for over 4 years.
The concept of the possession mechanic was inspired by the game Earthworm Jim, where, on one of the levels, the protagonist loses his armor and is vulnerable and helpless until he finds it again. The developers liked the feeling of changing from a weak character into a powerful one.
MarketingThe distributor, Virgin Interactive, came up with a magazine ad depicting Pope John Paul II smoking a cigar, with the tagline "What's possessed you? Messiah". Two magazines refused to run this somewhat controversial ad.
ReferencesThere is a scene that has you possess a worker in a radiation suit. When you approach some guards, they call you "Half Life." This is a reference to the game Half-Life.
One of the in-game locations is named "Club Kyd", after Jesper Kyd who composed the game music.
TechnicalMessiah's engine is a lot more advanced that what it first may seem. It featured a LOD function (Level Of Detail) that would modify the polygon count in the scene in real time while the player was playing to keep the frame rate smooth. The faster your PC, the more polygons the engine would put in the models making them smoother. And you can see the adding subtraction of polys as you are playing.
