This is a large, open map that is good for 5v5 and up.  It survived being voted off of the world's most popular custom map regular weapons CTF server for almost a year and has been played in 5v5 clan-match style PUG matches and often resulted in good games, some of which went into overtime. It's also good for low-gravity sniper and instagib.  Don't let the name fool you; it's about the same size as CTF-Orbital.
