The metro.zip file you have requested: Maps Levels Missions / Deathmatch / M Titles / metro - 1.49mb is not available. Perhaps try browsing all files for the game Quake III Arena and upload any files you want to share or are missing. This is the only information we could locate:
Quite large but very flat and fast city based level. Uses custom textures from Rungy's tutorial (www.quake3mods.net /rungy). Like no other Q3 map made.
