LithTech


LithTech is a 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 , released in 2014.
After the release of Middle-earth: Shadow of Mordor, the studio started working on a new engine for larger-scale battles called "Firebird".

Versions

LithTech 1.0

Originally the LithTech engine was supposed to be called DirectEngine, as Monolith was developing it for Microsoft to be included as a 3D engine for use with Microsoft's DirectX technology. When Microsoft decided not to use the engine Monolith bought back the rights to it and continued development on their own. They changed the engine's name to Lithtech and licensed it to other companies. In the following years, the LithTech team was split off into a separate company, LithTech Inc., which was renamed Touchdown Entertainment in March 2003.

LithTech 2.0

Starting with LithTech 2.0, LithTech Inc. began the process of creating many different versions of the engine. Monolith released their game No One Lives Forever featuring this version of the engine, however it was later revised to LithTech 2.2. The game received an upgrade to LithTech 2.2 in a patch release. The LithTech team then continued to improve version 2.2 for its licensees, resulting in the 2.3 and 2.4 iterations.
LithTech cooperated with RealNetworks in developing a custom version of LithTech 2.2 called RealArcade LithTech. Among its features it supported streaming media for in-game billboards/ads, and could be used with RealNetworks' gaming site. At one time, RealArcade LithTech could be licensed by developers if they signed an agreement with RealNetworks. This engine was used on an internally developed title, Tex Atomic's Big Bot Battles.

LithTech Talon

LithTech Inc. developed a different engine specifically for Monolith's title, Aliens versus Predator 2. LithTech Talon was based on LithTech 2.2, rather than LithTech 2.4. Because of this choice, LithTech 2.4, RealArcade LithTech, and LithTech Talon became largely incompatible with each other. However, reviewers still thought of it as inferior to Unreal or id Tech.
LithTech Talon's biggest selling point lay in its capable multiplayer support, more efficient when compared to prior versions of LithTech multiplayer that featured poor networking code. Aliens versus Predator 2 features comprehensive multiplayer gameplay utilizing these improvements.
By 2003, Talon was still being licensed.

LithTech 3.0

LithTech 3.0 was being developed concurrently with Talon, but, along with its revisions, LithTech 3.x would largely be considered an internal version of the engine. While it was sent to licensees, no games were finished on it. The primary feature announced for LithTech 3.x was the Distributed Object System, a new system for MMORPGs and multiplayer. Unfortunately, LithTech 3.x was also plagued by a significant number of bugs and problems and all games developed with LithTech 3.x would eventually convert to the newer LithTech Jupiter or to Talon.
The unreleased Monolith game Shogo II was being developed with this iteration of the LithTech engine.

LithTech Discovery

LithTech Discovery was created with the MMORPG genre and its unique requirements in mind. Discovery improved upon the working technology from LithTech 2.2, but also included the Distributed Object System which was the centerpiece of LithTech 3.x. The only game title to be powered by LithTech Discovery was The Matrix Online by Monolith. The engine was never licensed to any other company.

LithTech Jupiter

LithTech Jupiter was a thorough overhaul of the LithTech technology, developed as an alternative to 3.x. In some ways, the original version of Jupiter was even more technologically advanced than its competitors, since it supported Shader Model 1.x and included a visualization tool, whereas at the time Unreal and Quake only supported CPU-based shaders.
A custom version of Jupiter was made especially for Monolith, for use with their Tron 2.0 game; this release was codenamed LithTech Triton. Eventually, LithTech Triton's new features were merged back into LithTech Jupiter for licensees.

LithTech Jupiter EX

As of 2005 the latest public iteration of the LithTech engine was Jupiter Extended, which was featured in F.E.A.R. and , both developed by Monolith. Compared to its precursor Jupiter, the Extended version was driven by a new DirectX 9 renderer and other advancements, including the addition of Havok physics software for improved real-world physics simulation, dynamic per-pixel lighting, bump mapping, normal mapping, and specular highlighting. Along with Havok's character dynamics, Jupiter EX also includes the "Havok Vehicle Kit", which adds support for common vehicle behavior.

LithTech Firebird

Firebird was created with purpose of larger-scale battles and the expansion of the Nemesis system for .

This is also the version of the engine used in the development of the LithTech Film Producer machinima tool by Strange Company, most notably used in their short film "Ozymandius". Later development switched over to LithTech 2.0 however.
