The player takes the role of a diamond thief named Fingers Lonegan. The game starts at Lonegan's car in the top left hand corner of the opening screen. The player must make their way to the Acme Diamond Company building at the bottom of the screen by negotiating the garden maze. Police appear from the Police station and will home in on and arrest Lonegan. To avoid being arrested, the player must shoot the police. Bullets are limited but can be replenished by going back to the car. The player may also enter the mine or the police station from this opening screen. There are many diamonds to collect which are on many levels of the Acme Diamond Company building as well as the mine. Police enter the building but not the mine where the only enemies are ghosts. The player may also enter the police station and free fellow robbers. There are basic puzzles such as collecting keys, TNT, torches and the code for the safe to advance in the game.
Reception
The game was criticised for the fact that you shoot and kill many policemen. At the time, this was highly controversial as video games were very much seen as being for children. Rog Frost in Electron User wrote, "I find this game wholly inappropriate. It strikes me as abhorrent that success is measured by the ability to shoot policemen or steal diamonds. It should have been given a fantasy setting where the nasties which must be shot are not recognisable as creatures from the Earth". This view was shared by Ray Sharp of Atari User as "shooting policemen is not my idea of a good thing to teach children to do. Aliens from a distant planet OK but not your neighbourhood bobby". The game also received almost universally negative reviews from critics at the time. Electron User awarded an overall mark of 4/10, complaining "The graphics aren't really up to par, even for software at this price. The sprites are simple and undergo a sort of jerky animation... The scenery that supports the action can probably best be described as plain or perhaps boring". Atari User awarded only 2/10 overall concluding "The graphics are pathetic and the sound effects dismal. The game is playable but not for long... it's a disaster". Zzap!64 gave an even lower score of 9% claiming it to be "The worst program we've seen on the 64".
