The Mesa City game was one of five Flash games located on the original Sly Cooper and the Thievius Raccoonus website. In the game, the player must protect Murray as he makes his way through Muggshot's turf.
The goal of the game is similar to that of "Murray's Big Gamble." The player controls a turret and covers Murray from afar as he encounters several guards. Though the turret is intended for use against enemies only, it can also kill Murray if the player is not careful. There are drums located along the path that can be blown up with the turret. Their explosions can also kill Murray if he is too close to them. There are no checkpoints, and Murray dying will result in having to restart from the beginning.
