Casino City is a fictional location and playable stage that made its debut in the original Vigilante 8. The setting is a large, bright part of Las Vegas in the early morning hours with a collection of casino and royal based architecture and landscape. The area is surrounded by massive buildings, hotels, a gas station, twisting highways, blimps and an assortment of lighting fixtures set up among the outer regions of the area. It even includes a lower-scale replica of the Taj Mahal, which is accessible to the player. Hazards within the stage include potholes, which when contacted with, shoot steam at a high intensity and causes the player to both take damage and project them off their path and all the buildings of the city, that explode when destroyed dealing damage to players or enemies that are too close or on the top of them.
- Certain hotels and the replica of the Taj Mahal are accessible through destruction. Paths open to reveal plentiful sources of Special Weapon Crates, Wrenches and Power-Ups.
- The blimps sorted around the stage are accessible through a chute in the rear that can be shot open. Once inside, the player can then take control of the blimps in order to set themselves up to collect Special Weapon Crates and Wrenches located on top of buildings. The blimps will return to their original position upon evacuation.
