Blood Money is a side-scrolling shooter video game developed by DMA Design and published by Psygnosis in 1989 for the Amiga, Atari ST, and MS-DOS. A Commodore 64 version followed in 1990. The game is set in four different locations on a planet, where the player must fight off enemies and bosses. The game began development immediately after Menace, and borrowed similar gameplay elements. The development team used advanced hardware to develop Blood Money, using improved graphical and technological processes. The game was inspired by the presentation of Mr. Heli, and the animations of Blood Money would later inspire the development of Lemmings. The game was released to positive reviews; praise was given to the game's graphics and gameplay. The game was commercially successful, selling over 40,000 copies. Gameplay Blood Money is a 2D side-scrolling shooter. The player moves through four stages on the planet, taking control of a different vehicle in each level: a helicopter in the metal world, a submarine in a water world, a spacesuit in an ice world, and a fighter jet in a fire world. Each vehicle features unique weaponry, which the player uses to attack all advancing enemies. The player can upgrade their vehicle with power-ups, which grant them additional weapons and upgrades, such as support missiles and neutron bombs. The vehicles' energy acts as the player's health, and is depleted when the vehicle makes contact with enemies and walls. When all energy is lost, the player lose a life; three lives are provided at the beginning of the game, and additional lives can be bought in a shop at certain points in the levels. Money for the shop can be collected when destroying enemies. When all three lives are lost, the game ends and the player are sent to a score result screen. The first two levels may be selected from the beginning of the game; after one level is complete, the player can select any remaining world without restrictions. At the end of each level, the player must defeat a boss. Development Following the successful release of Menace in 1988, David Jones began developing Blood Money on 4 January 1989, on the 25 MHz 386-DX computer that publisher Psygnosis granted him, alongside a Personal Development System. Jones saw Blood Money as a continuation of the concept used in Menace. Jones was heavily inspired by the "cuteness" of Mr. Heli (1987) during the
