Cyberswine follows the titular character on his first day on the police force of CyberCity together with his partner Sara Lee, a human police officer who isn't happy to be showing a pig the ropes. The pair soon discovers a plot to release a virus that would kill nearly everyone in the city and races to stop it.
Billed as a "Multipath movie," the game consists entirely of cutscenes with players asked to influence decisions at predetermined times, such as whether to engage a suspect aggressively or calmly. Most decisions cause only minor differences in the scene immediately after the choice, with no impact on the overall story. Even with no input, the game will complete the story on its own.
