This is a PAK file that contains seven freely-available third-party Quake maps that have proven to be very good for Internet deathmatching, with about 6-12 players (depends on the map). The maps are anihous2 (anihouse version 2), clean01, dcdm3, kndycity, dcdm5a, and deguello. It also contains the client-side files necessary for playing on a server that supports the custom models and sounds for the AirFist weapon. The way we recommend using this PAK file is to put it in your id1 directory and rename it to pak2.pak. If you already have a pak2.pak (??), then name this file pak3.pak instead. Etc. For information about these maps and about an Internet server that is using them (and the AirFist), see http://lemur.stanford.edu/clan9/frames/index_inv_e.html -- but then, that's probably the page you got this archive's URL from in the first place... Alternately, you can get an archive of these separate files (not in PAK format) as c9ex_fls.zip. Brought to you by Clan 9 From Outer Space!
