The Operative: No One Lives Forever: 3 Open Source Clones Compared
The 'The Operative: No One Lives Forever' entry itself is Monolith's original 2001 GPL source-code release of the game, including its level editor, but built specifically for game version 1.003. No One Lives Forever Modernizer is a different kind of project — a patch for the actual retail installation (which it requires you to already own) rather than a source reimplementation, adding quality-of-life fixes like working multiplayer and a jukebox. lithtech is a separate, still-early effort to build a modern engine around the differently-licensed 'Jupiter Ex' GPL release that originally shipped with NOLF2 and Tron 2.0, not the original NOLF1's own codebase; only the NOLF2 game code currently builds, and porting the original NOLF1 onto it remains unfinished.

Known limitations
- compatibility: Debug builds of NOLF2 trigger exceptions in the standard library, likely due to Microsoft's secure CRT differences.
- compatibility: NOLF2 retail data files differ from those supplied with the GPL release; not all retail data formats are supported.
- audio: Linux builds require DXVK-native to enable audio rendering.
- compatibility: Non-QWERTY keyboard layouts are not properly supported due to Lithtech engine limitations.
- features: Controller support is bare bones and only partially implemented during gameplay.
