Keen Software House

The first big project for Keen Software House was Miner Wars 2081, which was presented at Game Developers Conference in 2012.[6] The game received mixed reviews by critics.[7][8] Miner Wars 2081 is an action-survival space-shooter set in the year 2081, 10 years after the destruction of all planetary objects in the Solar System. The story introduces the player to many types of missions: rescue, exploration, revenge, base defense, theft, transportation, stealth, search and destroy, pure harvesting or racing.

The source code for Miner Wars 2081 was released in March, 2013, under a commercial (non-copyright, restricted-use) license.[9] The code may only be redistributed to allow for "mods" of the original game, and the code must continue to perform a license-ownership check.

The studio's second project, Space Engineers, is a voxel-based sandbox game that launched on Steam Early Access in October 23, 2013,[10] and released on February 28, 2019. The game presents the player with an open world asteroid field wherein they can mine resources, build ships and stations, play with physics, and much more. Space Engineers is a sandbox game about engineering, construction and maintenance of space works.[11] The game sold more than 500,000 copies by May 6, 2014.[12] Space Engineers was well-received by both critics and the gaming community.

During the majority of its developmental life, Space Engineers was updated on a weekly basis based on stated development goals and community feedback. Since initial launch it experienced major updates adding survival mode, multiplayer, dedicated server support and more. Space Engineers is open to community creation and modding.

On October 20, 2014, Keen Software House announced that Space Engineers had sold over 1,000,000 copies.[13]

On May 14, 2015, the development firm provided open access (but not making the game free) to the source code to accelerate mod development.[14]

On February 28, 2019, the game was officially released and continues to enjoy periodic software updates.

On January 13, 2015, Keen Software House announced their third title and second engineering game named Medieval Engineers.[5] It was also announced that the game will be available on Steam Early Access.

Medieval Engineers is a sandbox game about engineering, construction and the maintenance of architectural works and mechanical equipment using medieval technology. Players build cities, castles and fortifications; construct mechanical devices and engines; perform landscaping and underground mining.

Medieval Engineers is inspired by real medieval technology and the way people survived and built architectural and mechanical works in medieval times. Medieval Engineers strives to follow the laws of physics and real history and does not use technologies that were not available from the 5th to the 15th century.

On March 17, 2020, Keen announced that Medieval Engineers would leave the Early Access stage, even though the game had no major updates since February 2019, and with only an update to fix major bugs and stabilisation on release date.[16] This caused an uproar in the Medieval Engineers community, making players turn to review bombing the game on Steam.[17] The game has never seen a worse month than March, with 85 percent of the reviews being negative, only to see a slight improvement in April (76 percent negative reviews).[18]
