The Sith Lords Restoration Project

The Sith Lords Restoration Project, commonly abbreviated as TSLRP, is a modding project for Star Wars: Knights of the Old Republic II: The Sith Lords developed by a group called Team Gizka. It was named after the in-universe Telosian Restoration Project.

The modmakers aim to make the game closer to Obsidian Entertainment's original vision, which they were forced to deviate from due to time constraints. This includes restoring missing content, such as the Cut Ending to Knights of the Old Republic II, the HK Manufacturing Plant, and other removed subplots, as well as fixing bugs (including broken quests) present in the retail version.

Cut content that will not be restored includes the planet M4-78 and a cutscene involving confrontation between Darth Nihilus and Darth Sion (who believes he killed the Jedi Exile). However, the Team Gizka forums spawned a separate modding effort, the M4-78 Restoration Project, focused on bringing the droid planet (along with the original subplot for Jedi Master Lonna Vash) back into the game.

Despite being given no recognition by LucasArts or Obsidian, the Restoration Project sparked a lot of interest in the KotOR community. The thread dedicated to the project was made sticky on the official Obsidian forum, and a number of Obsidian and Holowan Labs visitors have said they are looking forward to playing KotOR II the way it was meant to be played.
