Team Fortress 2/Walkthrough

Team Fortress 2 launched with six official maps, expanded to eight with the release of ../cp_badlands/ and ../pl_goldrush/. Additionally, the ../cp_well/ map received something of an upgrade when it was duplicated to provide another CTF map. Also, Valve added two community-created maps, ../cp_fastlane/ and ../ctf_turbine/, to the official maps in a June 2008 update. In August, six new official maps (../pl_badwater/, ../arena_lumberyard/, ../arena_ravine/, ../arena_granary/, ../arena_badlands/, and ../arena_well/) plus another community map, ../cp_steel/, were added to the roster.

In February 2009, three more community maps — ../cp_junction/, ../cp_egypt/, and ../arena_watchtower/ — were added to the official rotation.

In addition to Valve's maps, some servers host their own custom maps. If you join a server that has a custom map, you will automatically start downloading the map from their server. Even though these aren't Valve's maps, statistics are still kept on your matches.
