The Sith engine is a game engine developed by LucasArts. The game Star Wars Jedi Knight: Dark Forces II is based on this engine, and its expansion, Star Wars Jedi Knight: Mysteries of the Sith, is based on a slightly updated version. The engine has also been used in Grim Fandango as a basis for the GrimE engine, and used in Star Wars: Droid Works. A modified third-person view version of the code with drastically rewritten lighting, collision, rendering and tools was renamed to Jones engine and used in Indiana Jones and the Infernal Machine.

The Sith engine is an early example of a scripted game engine. Most object behaviors are implemented with the integrated COG scripting language or defined parametrically using a template system which allows simple inheritance. The engine is also an example of a portal engine. Level geometry is rendered as a series of negative-space convex polyhedrons connected by adjoining polygons. Levels require no preprocessing and hidden surface determination is computed at run-time.

Jk: Gunrunners is finally on ModDB!

The Dark Palace of Argenia

Effectively serving as a space to concentrate all my creative efforts, Jk: GUNRUNNERS completely transforms the experience of the game, adding elements from many other gaming genres including RPG and racing. As a Total Conversion, it has no relation to the Star Wars or Jedi Knight storylines, being instead based on a story of my own.

I'll try to keep this page updated with significant news as well as images and videos, with playable development snapshots coming out every once in a while.

I heard a version of the SITH engine was used for Indiana Jones and the Infernal Machine. It'd be great if someone made an emulator of some kind for it cos it has so many problems on modern machines.
