Mean Streets was the first of a series of games featuring Tex Murphy as the protagonist. Mean Streets, which was released in 1989 by Access, was the only one in the series available on the Commodore 64. This was one of those games I always wanted but never got to play. What's not appealing about a post-apocalyptic cyberpunk mystery? In addition to being available on the Commodore 64, it was also of course available on DOS based PCs where it was first developed. It was also ported to the Amiga and Atari ST but only in Europe for some reason.
The game is essentially a graphic adventure but there are other elements, including even a 3D flight sim. You, as Tex Murphy are investigating the mysterious death of a college professor who was seen falling from a bridge and had previously been working on a secret project. The police think it was suicide but his daughter is convinced it was murder.
The PC version was one of the first to support 256 color VGA graphics on the PC and also introduced a technique for creating digitized voices and other advanced sound using just the PC speaker without a sound card. The Commodore 64 version paled in comparison in these regards (though it seems they could have done better with the sound if they had wanted to). However, the consensus seems to be that the playability is nearly as good as the PC version and that's what is most important.
