Thirty-nine real Halo maps, and one that is not
The maps
A description is the only way anybody can find out what a place looks like, and what does it look like is a question this game otherwise has no answer to at all. These are the same text files the server sends to the game, read live: rewrite one on the server and it changes here.

Reading the descriptions…
—
Descriptions live in server/data/map_descriptions/ as plain
text files, one per map, named after the map. Anybody can rewrite one or
add their own without touching the game. In the game they are a strip
inside the documentation screen: tab into the section, arrow along the
maps, tab again and you are reading the one you landed on — starting on
the map you are standing on.
