Team Fortress 2 is the sequel to the game that put class-based, multiplayer team warfare on the map. It delivers new gametypes, a signature art style powered by Valve's next generation animation technology, persistent player statistics, and more.
This release also contains preview thumbnails and the intro movie. As such, it should be extracted from your base "team fortress2/tf/" directory, rather than the maps directory. Server Admins: If you do not want to have players download the movie file (which is understandable, because the map itself is already a large download), be sure to also remove those lines from the tc_meridian_rc3.res file in the maps directory.
