PrBoom-Plus is a modified PrBoom port with uncapped framerate, variable gamespeed, re-record, walkcam, chasecam, full mouselook, fov, hi-res and detailed textures and other features without loss of compatibility with original DOOM The target of the project is to extend the original port with features that are necessary or useful for me personally and to all those interested in my work. It is worth noting that all changes introduced by me in no way break PrBoom's compatibility with the original Doom/Doom2 engines, and it is possible to be confident this will never happen in the future since compatibility is as important a merit of PrBoom as it is to me.
Note: you need the original Doom data files to be able to play. Depending on your Doom version these are called doom.wad, doom2.wad, tnt.wad or plutonia.wad.
