Spintires

A spin-off game called MudRunner was released on October 30, 2017.

Spintires is an all-terrain simulation video game which tasks driving through muddy unpaved Russian roads in aging Soviet vehicles with nothing but a map and a compass. The aim of the game is to transport cargo to its destination without depleting resources (such as fuel) or damaging the vehicle. There is both a single-player and multiplayer mode. The game takes into account several properties such as physics, mud, terrain deformation, as well as driving controls and a day/night cycle. Due to the challenging terrain, players must take all conditions into consideration and drive accordingly; for example, they cannot simply just press "forward" on their keyboard to drive straight. Players can choose between casual and hardcore mode. In hardcore mode, fuel consumption is increased and routes the player charts on the map will not be displayed as a guide on the road as they drive. The game's camera is positioned outside the vehicle and can be moved around using the mouse; there is no in-car view.

Development was preceded by a demo game made by Pavel Zagrebelnyy for the 2009 Intel Level Up game development competition, where the game won the first prize in the 'Best Multithreaded Game' category and finished second in the 'best game optimized for Intel graphics' category. The game initially raised $82,684 on Kickstarter in 2013. A few days following its release, Spintires briefly became the top-selling video game on the Steam platform, and a month after it still retained a position in the Steam Top 10, selling over 100,000 copies. In 2014, developer Zagrebelny alleged that Oovee took the money and cut off communication, which left him unable to update it. Oovee, however, has denied the allegations, saying Zagrebelnyy has been paid in full for the work he completed and that there is no breach of contract on the side of Oovee. Later, both Oovee and Zagrebelnyy attributed the dispute to "communications issues", and said that an eventual sequel to Spintires was a possibility. In December 2015, Oovee opened up the game to its player base with Steam Workshop support, seeing the release of its truck and map editor. A news post on the Spintires Steam page by Oovee, suggested that Spintires was not over as many had suggested, and showed signs of further graphical improvements and additions to gameplay. Throughout 2019, Spintires has received numerous updates including fixes, graphical enhancements and DLC. As of 2022, the game is no longer available for purchase from Steam due to copyright disputes.

In 2015, Zegrebelnyy started working at Saber Interactive, a former employer of his, to aid development of MudRunner. and Oovee licensed the game to Saber Interactive. SnowRunner, sequel to MudRunner, was released in 2020. At Gamescom 2023, a new game called Expeditions: A MudRunner Game was announced. The game was released on March 5, 2024. A VR game titled MudRunner VR was also released on May 30, 2024.
