Awhile back playing The House of the Dead on a Model 2 Emulator, I digged inside the service test option to enter the sound test and found two unused soundtracks.
These two tracks could mean that there were two more levels in the game, but it was cut from the final production. Since were getting ports of the 3rd and 4th game on the PS3, should AM1 create a perfect arcade port or a complete remake of the game with 2 additonal levels with the tracks to keep the game brand new?
Honestly, I wouldn’t be surprised if there were supposed to be six chapters in the first THotD instead of four. Reason why? The Sound Test for Virtua Cop also features unused dialogue in the game for Rage, Smarty, and the bosses. The unused music tracks probably also explains why the three remaining Tarot cards (The High Priestess, The Devil, and The Moon) haven’t been used yet.
