Abuse
Abuse resembles a side-scrolling platform game. The game stands out for its unusual control system: The keyboard is used to move Nick around, while the mouse is used to aim the weapons. The basic gameplay consists of fighting various enemies (especially the different forms of mutants that prefer to attack in huge swarms) and solving some simple puzzles, which mostly involve switches.
Story
The game's protagonist, Nick Vrenna, is unjustly imprisoned in a prison where the staff carry out unethical medical experiments on the inmates. A prison riot breaks out and an experiment goes horribly wrong. The people in the prison - with the exception of Nick, who seems to be immune - are infected with a substance called Abuse, which turns them into monsters. Nick takes a laser gun and single-handedly destroys all the mutants, prevents the substance from spreading further and escapes from the prison complex.
