I really appreciate the work that went into redeeming CTF (even if it ends up being overshadowed by its pluckier younger brother Rugby).
The perennial problems with CTF that tim mentioned can't be helped (since we can't use Lua to make newbies play better or drop out less).
However, the infamous lag of CTF 4 concerns me. Is it native to CTF mode, or does it have to do with the 909 lines of Lua in this script? My reservations lead me to deduct one star.
This is a lua script that enhances the CTF gametype so it doesn't suck. I wrote the original CTF script, and Irons added some cool features along the way. The readme included explains everything in detail.
