Good night, DeFrag [.df]

Defrag is a free software modification, released around 2000, that transforms the base first-person shooter into a precision platforming and movement challenge. The core gameplay loop involves mastering complex aerial maneuvers and speedrunning custom maps to reach finish lines, rather than combat. Distinctive features include integrated timers, ghost mode for self-training, and support for physics from both the original game and the CPMA mod, making it a specialized tool for skill refinement and trickjumping competition on PC and Mac.
