This is all just from memory, but from the screenshots it appeared to be a kind of cyberpunk point & click adventure, with some combat elements. At the beginning of the game the player would wake up after some kind of invasive cybernetic surgery, the result being the walking equivalent of a (brown?) forklifter (more invasive than System Shock and definetly not as handsome as robocop). I also remember a fairly cool looking screenshot of the player fighting some kind of cybernetically enhanced velociraptor. There was also something about the main character being very enraged about whoever or whatever did the surgery on him and that he had to save someone from a certain (similar?) fate.
The thing is, and this is what makes my search interesting, I seem to remember that its title was a bit similar to 'System Shock'. Except it had 'Bio' as a prefix, indicating a prevalent theme in the game. Bioshock? It can't be..
