I needn't explain what CTF is. This pack is a compilation of several packs, really. First it has four old (and pretty bad; I strongly suggest you NOT to test MLEB) levels from 2001 and 2002. Then it has the christmas pack which CC' assembled for the christmas server at 2004; consisting of five levels. Lastly, there's the small NLM pack from 2005.

Because the filesize would get too big otherwise; I cut the pack in three parts.
