Angel Quest is a cancelled action adventure that was in development by french company Virtual Studio (Ar’Kritz the Intruder, S.T.O.R.M.) around 1996 / 1997, to be published by GT Interactive (Driver, Oddworld: Abe’s Exoddus, Critical Depth) for Playstation and PC. You could freely explore a huge (for its time) 3D world by flying around with its winged protagonist, somehow similar to a 3D Kid Icarus. You would fight against enemies in real time, helping NPCs and resolving quests as in a classic Action RPG.
As far as we know GT Interactive never officially announced this project, but thanks to Stéphane de Luca who shared some images and details on his website, we can preserve the memory of this lost game:
“This project was the first to use optical motion capture for real time animation: we pioneered this advanced technology. The heroes was an Angel living in a very large world: he could make use of his ability to fly to speed up its move towards the next location to visit. Numerous characters were also there to help him find his way, giving him potential clues through interactive dialogs.
Angel Quest was running on PlayStation on which I programmed the engine and the game in C and assembler. All the characters were in 3D and animated through motion capture: I developed a compression tool that reduced the data stream (curve) that was moving each node of the skeleton. The word was really huge: I had to stream all blocks silently from the CD-ROM drive as the heroes was moving: it was a big challenge due to bandwidth limitation.”
