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. Plot 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 - are 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. Gameplay Abuse resembles a side-scrolling platform game. The keyboard is used to move Nick, while the mouse is used for aiming the weapons. The gameplay consists of fighting various enemies (mostly the various forms of mutants, who prefer to attack in huge swarms) and solving simple puzzles, usually involving switches. Networked play, through IPX/SPX, is supported. 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. The game was in development for 6 months by three people with a budget of $150,000 Release Abuse was originally released on February 29, 1996 for MS-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 on March 5, 1997. The port was largely reworked for Mac, with the graphics partially redone to work better in 640x480 resolution. Source code release Approximately
