Pyoro is a 2015 indie supernatural horror video game developed by Lollipop Studio for Microsoft Windows and macOS. Set in the autumn of 2005, players assume the role of Vladimir Smirnov, a scientist who must escape the Makarov Research Facility after it is invaded by a titular, small robot named Pyoro.
Pyoro was released on October 3, 2015 to critical acclaim. YouTubers such as Markiplier, Luigikid Gaming and Jacksepticeye played the game in their videos and got more than 5 million views. It went on to spawn a franchise with its prequels, sequels, spin-offs and an animated television series co-produced by Williams Street and Crossover Films Co., Ltd. that aired on Adult Swim from late October 2015 to December 2019.
In autumn 2005, Russian scientist Vladimir Smirnov—secretly a Disney, anime and robot fan—arrives late for work at the Makarov Research Facility, a Moscow-based secretive organization dedicated to containing any anomalous artifacts, entities, and locations that threaten the normality of the world. At his office, rebellious officer Igor Turgenev decides to call for Smirnov, their mole in the facility, to get them inside. Sergeant Mikhail Kuznetsov is skeptical that Smirnov will honor his word, but Turgenev insists that he will get them through.
As part of an experiment, Smirnov is summoned to perform a test on a small-but-creepy robot, known as Pyoro, that can move at high speeds and attack by causing cervical fractures at the base of the skull or strangulation when not in the direct line of sight of a person.
During this testing routine, the site's power and door control systems begin to malfunction, allowing Pyoro to severely kill scientists and escape into the ventilation system while, by player control, Smirnov escapes the containment chamber. Surviving scientists urge Smirnov to head to the surface, where he defends himself against hostile robots and Russian Armed Forces soldiers sent to cover up the incident.
