Abuse is a run and gun video game developed by Crack dot Com and published by Electronic Arts in North America and Origin Systems in Europe. It was released on February 29, 1996 for MS-DOS. A Mac OS port of the game was published by Bungie and released on March 5, 1997. The game's source code, along with some of the Shareware content, has been in the public domain since the late 1990s and has been ported to Linux and many other platforms.
The protagonist of the game, Nick Vrenna, has been unjustly incarcerated in a prison where the staff are performing unethical medical experiments upon the inmates. A prison riot occurs and an experiment goes horribly wrong. The people inside the prison - except for Nick, who seems to be immune - get infected with a substance called Abuse that transforms them into monsters. With the water supply in danger of being infected, Nick arms himself and fights through the horde to prevent this, and then escapes from the prison complex.
Abuse resembles a side-scrolling platform game. The game is notable for its (at the time) unusual control scheme: The keyboard is used to move Nick, while the mouse is used for aiming the weapons. The basic gameplay consists of fighting various enemies (mostly the various forms of mutants, who prefer to attack in huge swarms) and solving some simple puzzles, usually involving switches. Networked play, through IPX/SPX, is also supported. The game originally had support for TCP/IP play, but this was not present in the retail version.
Active zone
To improve the performance of Abuse's graphics engine, the code only allows objects within a certain radius of the visible game window to be active during play. This means that free-roaming enemies and always-on mechanical devices outside the radius cannot attack the player, nor will projectiles fired from weapons that ostensibly have an "infinite range" continue their journey much beyond the edge of the screen.
Development
Abuse had a very different storyline coming out of production. The update for it replaced the original introduction with the current storyline. The original involved an invasion by an alien species called "ants". The player was a special ops agent, sent into their 'hive' to covertly destroy the aliens by shutting down the cooling system. This story was alluded to in a hidden section towards the end of level 14, where a large area, full of maroon tiles, can be found.
Release
On February 29, 1996 Abuse was originally released for DOS and Linux as an incomplete shareware version by Electronic Arts in North America and Origin Systems in Europe. The game was ported to Mac OS by Oliver Yu of Crack dot Com and published by Bungie Studios on March 5, 1997. The port was largely reworked for Mac, with the graphics partially redone to work better in the 640x480 resolution.
Source code release
Approximately two years after the release of the game, Crack dot Com decided to release the game's source code. Also the shareware release's game data (excluding the sound effects) was handed into the public domain.
Community development
Based on the source release the game's community worked initially on maintenance work, e.g. making the game work over TCP/IP. In 2001 Abuse was adapted to SDL multimedia library, with other technical refinements like more than the 8-bit color depth the original version was limited too. The SDL version allowed easy porting to modern platforms, for instance Microsoft Windows, Linux/X11 and also the Mac version has been updated to run on OS X. Over the years, the game became available for many more platforms, for instance BeOS, Nintendo Wii via Wii homebrew. and in 2009 AmigaOS 4. The game has also been ported to the mobile devices, to iPhone/iPod Touch under the name Abuse Classic. Until 2011 the game was maintained by Sam Hocevar on his webpage. In 2014 the game was ported to SDL2 and transferred to a GitHub repository. In 2016, on the 20th birthday of the game, a community developer released a "20th anniversary source port" on base of the previous works which enabled custom resolutions, OpenGL rendering, Xbox 360 controller support and fixed the music.
