The Cacowards are the best source of quality levels and gameplay mods for Doom. Anyone who wants to expand their experience of Doom engine gameplay should look there for the best mods and levels. That isn’t to say that it covers all quality content, but it’s certainly a good start.
Special mention for the 2x upscaling project – a project that uses multiple AIs in tandem to redraw the Doom sprites at double the resolution.
