What This Actually Is

This cabinet runs on Freedoom, a completely free, open-source set of levels, textures, sprites, and sounds built specifically to be a legal, redistributable substitute for id Software's commercial game data. It's paired with PrBoom, a Doom-compatible engine that id Software itself released as open source in 1997.

Nothing from the retail id Software / Bethesda release is included or hosted here — no copyrighted levels, art, sound, or music. If you'd rather play with the original commercial assets, that's on you to source from a copy you legally own; this page won't be adding that.
