Mean Streets is a graphic adventure game developed and published by Access Software for MS-DOS in 1989 exclusively in North America.

The game, set in a dystopian cyberpunk neo-noir world, is the first in the series of Tex Murphy mysteries; its immediate sequel is Martian Memorandum.

The player plays the role of Tex Murphy, a down-and-out private investigator living in post-apocalyptic San Francisco.

Prior to his death, Carl would not talk to his daughter about the secret project he was working on, and days later, he was seen falling off the Golden Gate Bridge.

Once the code has been entered, the destination is marked by a flashing square, and the player must either guide their speeder to it or enable the autopilot.

Both Tex and enemies can crouch to hide behind the boxes and other debris which litter the streets, protecting them from gunfire but preventing them from hitting their targets as well.

The player's primary objective is to collect information about a scientist, Carl Linsky, and the conspiracy behind his apparent suicide.

Each sidequest consists of a side-scrolling shooter stage in the usual format, but with enemies which fire much more rapidly than those found on the main story path.
