Quarantine is a 1994 racing/first-person shooter video game for MS-DOS and 3DO, created by Imagexcel and published by GameTek. Versions for the Japanese market were done in 1996 by Asmik for the PlayStation and MediaQuest for the Sega Saturn, renamed as Hard Rock Cab and Death Throttle respectively. In the game the player drives a taxicab through a post-apocalyptic city, picking up customers and killing enemies. The game was continued with the sequel, Quarantine II: Road Warrior, which largely kept the original gameplay, but introduced a more mission and story-driven gameplay. Plot KEMO city was known for the manufacture of hovercars, meeting the country's demands for transportation until 2022. Over time, however, the crime rate had risen so far that the economy collapsed and the city descended into disorder. Criminals roamed the streets in armored hovercars, terrorizing the citizens 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 OmniCorp decided to test the behavior altering chemical Hydergine 344 on the population of KEMO. This chemical was supposed to pacify the citizens and distributed through the city's water supply. Unfortunately, OmniCorp failed to predict the chemical's reaction to stagnant water, resulting in massive brain damage and insanity in the many citizens. More than half the population became crazed killers overnight. Drake Edgewater, a 21st-century 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 vehicle-mounted weaponry, he delivers passengers and packages for what money he can make to upgrade his vehicle and escape. Gameplay The primary gameplay loop of Quarantine consists of using a weapon-equipped taxi to pick up passengers, deliver packages, and defeat enemies. In between missions, the player replenishes the taxi's ammunition and armor by visiting service stations, marked on the player's map. Missions send the player through Kemo City's various districts.
