Abstract
Doom 3 (2004) introduced the PK4 file format as the primary container for game assets. Building upon the PK3 (ZIP) format used in Quake III Arena, PK4 files organize textures, models, sounds, scripts, and shaders. This paper examines the structure, compression, and modding implications of PK4, highlighting its role in efficient content management and the game’s enduring modifiability.
Inside the .pk4 files (e.g. pak000.pk4 – pak004.pk4 for DOOM 3, plus game00.pk4 for scripts), you’ll find: doom 3 pk4 files
