jailbrekb: MAME ROM Information.


Jail Break (c) 1985 Konami.

A mass prison breakout has occurred and the prison warden has been kidnapped in this sideways scrolling shoot-em-up from Konami. The player controls a lonely police officer whose job it is to kill the hordes of escaped convicts and, eventually, rescue the kidnapped warden. Each level also has a number of civilian hostages that also roam the levels and need to be rescued.

The player begins the game with only a pistol, but 2 extra weapons, in the form of a bazooka and a tear gas gun, can be collected. The 'Weapon Select' button cycles through the player's weapons via a display at the bottom of the screen. When the desired weapon is highlighted, pressing the Fire button will select and fire the desired weapon.

Hostages will randomly run across the screen and can be rescued by running into them. Should the player accidentally shoot a hostage, all extra weapons will be lost leaving only the pistol.

This game is known in Japan as "Manhattan 24 Bunsho - NY 151 Nishi Dai 100 Street".

Jail Break's premise of a city overrun with convicts and a kidnapped ViP is based upon John Carpenter's 1981 film, 'Escape From New York'.

Donn Nauert holds the official record for this game with 185,900 points.


* Easter Egg : From the beginning of the game, rescue four hostages in a row; you have to do this to get the tear gas gun. Shortly after getting the fourth hostage, there will be a convict shooting down at you from a building. He is the first window shooter in the game, shoot him with the Tear Gas gun and you will be 'rewarded' with a brief glimpse of a topless woman. This also occurs at other points in the game.
