Quarantine is a 1994 first-person shooter created by Imagexcel and published by GameTek. It can be considered as race game as well because the main gameplay is revolved around driving a car.
The story of Quarantine happens in a city called KEMO. KEMO was known for the manufacture of hovercars, meeting the country's demands for transportation until 2022. Over time, however, KEMO's crime rate had risen so far that the economy collapsed and the city descended into disorder. Criminals roamed the streets in armored hovercars, terrorising the citizens of KEMO without fear of retribution.
In 2029, OmniCorp promised city officials that it could clean up KEMO and return it to normal. The offer was accepted, and the corporation began the construction of a massive wall around the city under the guise of a "defensive measure". The wall was completed three years later, and the only exit sealed shut, turning KEMO into a massive prison city for all inside, criminal or otherwise. The outraged population reacted violently, and the city degenerated.
Ten years later, in 2043, OmniCorp decided to test the behaviour altering chemical Hydergine 344 on KEMO. This chemical was supposed to pacify the citizens of KEMO, and was distributed through the city's water supply. Unfortunately, OmniCorp failed to predict the chemical's reaction to the stagnant water, resulting in massive brain damage and insanity in the many of KEMO's citizens. More than half the population became crazed killers overnight.
We play Drake Edgewater, a cab driver and one of the lucky few unaffected by the spreading virus, is desperate to escape the city alive. Driving his '52 Checker "hovercab" armed with an assortment of headlight-mounted weaponry, he delivers passengers and packages for what money he can make to upgrade his vehicle and escape.
The success of Doom by Id Software in 1993 led to many other companies attempting to follow Doom's success. Most ended up making unsuccessful debut, but Quarantine was one of the few games that successfully exploited the features of Doom with its own texture mapped stages and vehicular combat gameplay.
