LithTech

LithTech is a discontinued game engine developed by Monolith Productions and comparable with the Quake and Unreal engines. Monolith and a number of other video game developers have used LithTech as the basis for their first-person shooter games. Monolith initially developed the engine for Microsoft before purchasing the rights to it and licensing it to other developers via subsidiary LithTech Inc. The licensing company was renamed to Touchdown Entertainment in 2003 and later absorbed into Warner Bros. Interactive Entertainment after its acquisition of Monolith. The last version of LithTech offered for licensing was Jupiter EX, initially released in 2005, however Monolith has continued to use LithTech technology in their games, including Middle-earth: Shadow of Mordor, released in 2014. After the release of Middle-earth: Shadow of Mordor, the studio started working on a new engine (based on LithTech technology) for larger-scale battles called "Firebird". LithTech technology has been effectively discontinued with the closure of Monolith Productions on February 25, 2025.
