Due to the game's age, most visual mods focus on upscaling textures or fixing aspect ratios for modern monitors.

Hitman: Codename 47 (released in 2000) has a limited but dedicated modding scene. Unlike its sequels ( Silent Assassin , Contracts , Blood Money ) or the modern "World of Assassination" trilogy, Codename 47 lacks official modding tools. The engine (a modified version of the Glacier engine) is notoriously difficult to work with due to file archiving and a lack of documentation.

You cannot add new 3D models easily, but you can place existing objects using OBJECT_CREATE in scripts.
