Empire City: 1931 (エンパイアシティー1931), also known as Street Fight is a shooting gallery game that was originally released into arcades in 1986. The game has players taking on the mafia in 1931 New York City by gunning down mobsters one by one.

Versions of the game were released for the Family Computer (1987) and MSX (1988) as Magnum Kiki Ippatsu: Empire City 1931 (マグナム危機一髪 エンパイアシティー1931).Acclaim advertised a release for the Nintendo Entertainment System in Western regions, but the console version remained exclusive to Japan.

Seibu Kaihatsu eventually released a follow-up game, Dead Angle.

The game is set in 1931 New York City where the player controls a young man who must avenge his family members, who were killed in a gang shootout. Over a period of several months, he targets mobsters, culminating with the mafia boss.

Players move a crosshair around the screen to aim and shoot at mobsters one at a time. They lurk around various areas, including on the street and in windows. An arrow appears that helps direct players to the location of the next mobster onscreen. Players have a set amount of time to find and shoot each enemy; if time is running out, a speech bubble appears counting down the last few seconds on the timer. When the timer reaches zero, the player is shot and the screen pans to the location of the enemy. A defend button is available as a last resort to avoid being shot. Players can replenish their ammo by shooting hidden ammunition boxes and get bonus points by shooting at gold bars.

Levels are cleared after a set number of mobsters are eliminated. In the game's final level, the player has only one opportunity to assassinate the mob boss as he walks in front of windows in a building. After the final level is completed, the game loops back to the beginning.

The Famicom game is largely the same. The player's progress can be restored any time in the Famicom version by using a password system of four numbers and/or letters.
