Abstract The Max Payne series, developed by Remedy Entertainment and published by Rockstar Games, is renowned for its narrative depth, bullet-time mechanics, and technical modifiability. Central to the modding and file management of the PC versions—particularly Max Payne (2001) and Max Payne 2: The Fall of Max Payne (2003)—is the VPK (Virtual Package) file format. This paper provides a comprehensive overview of VPK files: their role in game data storage, internal structure, tools for extraction and repacking, and their significance to the enduring modding community. 1. Introduction Unlike modern games that use encrypted or proprietary archives, early 2000s PC games often employed semi-open archive formats to balance performance (reducing file fragmentation) with accessibility. Max Payne and its sequel use VPK files to store game assets, including textures, models, sound effects, level data, and scripts. The format’s relative simplicity enabled a thriving mod scene, including total conversions like Max Payne: Kung Fu Edition and Payne Evolution . 2. Purpose and Location of VPK Files In a standard installation of Max Payne or Max Payne 2 , VPK files reside in the game’s root directory. Common files include: Max Payne Vpk
