takedef

A takedef, short for "take definition," is a term primarily used in the context of first-person shooter (FPS) video games, particularly those based on the *Doom* and *Quake* engines. It refers to the process of modifying or replacing the default game assets, such as textures, models, sounds, and levels, to create custom content. This practice is common among players who wish to enhance gameplay, introduce new challenges, or simply personalize their experience.

Takedefs are typically achieved by extracting the original game files, editing them, and reintegrating the modified versions. In *Doom* and *Quake*, the game data is stored in WAD (Windows Archive Database) files, which can be unpacked, altered, and repacked using tools like *WADMer*, *PK3Edit*, or *Doom Builder*. Players often use these tools to replace default textures with custom artwork, adjust level layouts, or introduce new enemies and weapons.

The term "takedef" itself originates from the act of "taking" the game's definition files—such as those defining sprites, textures, or game logic—and "defining" them anew. This process allows for deep customization, enabling players to create entirely new games or modify existing ones. However, takedefs can also introduce balance issues, bugs, or compatibility problems if not done carefully.

While takedefs are legal under fair use and creative commons principles for non-commercial purposes, distributing modified content that infringes on copyright may violate game licensing agreements. Many developers and communities encourage responsible takedef practices, often providing official support or community-driven resources for customization.
