this stage." [ 165 ] There are two video games based on the film, one for Commodore 64 , Sinclair ZX Spectrum and Amstrad CPC (1985) by CRL Group PLC based on the music by Vangelis (due to licensing issues), and another action adventure PC game (1997) by Westwood Studios . The Westwood PC game featured new characters and branching storylines based on the Blade Runner world. Eldon Tyrell, Gaff, Leon, Rachael, Chew, and J.F. Sebastian are seen, and their voice files were recorded by the original actors. DNA Row, the Eye Works, the Police Headquarters, Howie Lee's, the Tyrell Corporation building, and J.F. Sebastian's hotel are faithfully replicated. [ 167 ] The events portrayed in the 1997 game occur not after, but in parallel to those in the film. The player assumes the role of McCoy, another replicant-hunter working at the same time as Deckard. Although Deckard is seen in photo evidence and referred to in dialogue, [ 167 ] Deckard and McCoy never meet. [ 124 ] [ 125 ] The PC game featured a non-linear plot, non-player characters that each ran in their own independent AI , and an unusual pseudo-3D engine (which eschewed polygonal solids in favor of voxel elements) that did not require the use of a 3D accelerator card to play the game.
