This is a mod I made for Doom, based on Xaser’s Parkour mod.
Parkour is another ‘mutator’ mod, which includes no graphic or sound assets, and uses GZDoom’s scripting and configuration functions to remix the existing assets into something new. Parkour features walljumping, dashing, and some remixed (and rather tongue-in-cheek) weaponry.
Parkour Lite retains the same overall feel, but features a weapon lineup that’s closer to the classic Doom arsenal.
It’s designed to run on fairly recent versions of GZDoom, though it might work on other ZDoom forks as well.
