A good sized Q3Fortress CTF map. All classes can be used to their fullest potential which makes for nice strategic games. The level is prime for 6 to 16 players, with a mixed team being the most successful. The layout is very CTF with a few ways into the flag room, good sized common ground and a few little secrets along the way.
Q3F anyone? Good for online or LAN parties. (requires Q3F, grab it here.)
