(originally posted 11.26.24 / updated 12.10.24)

Quake Live includes way more maps than Quake III Arena, many of which are community maps that were either ported over or remade. some of them recieved new names and significant changes that might not make it obvious, plus most of the time the filename is referenced rather than its actual name in Q3A. i couldn't find any around so this is a complete list of every QL map, which Q3A map its a remake/port of, QL-style levelshots, and links to download them.
(if the map isn't playable in vanilla Q3A, it'll be in a list without a levelshot below the main tables)
