Silent Chaos is a cancelled action adventure that was in development by Kalisto Entertainment from 1997 to 1999. The game was going to be published on the Playstation by Squaresoft, but originally the project started as a sequel of Dark Earth, an action adventure created by the same team and released only on PC. After few months of work on Dark Earth 2, Kalisto stopped the development for the PC, but it seems that Squaresoft was interested in the game and they changed DE2 into a new IP for the PSX.
The character designs that were initially created at Kalisto were redone again by Tetsuya Nomura, one of the main character designers at Square, famous for his works on Final Fantasy 7, Parasite Eve, The Bouncer and many more. Sadly, after a couple of years of development, Silent Chaos was canned, probably because of the shift of development on the soon to be released Playstation 2. A new Dark Earth 2 project was later proposed for the PS2, but nothing came from it. Kalisto Entertainment declared bankruptcy in 2002: Dark Earth 2 / Silent Chaos vanished forever with the studio and only few CG models and backgrounds remain.
