Ok, first of all, I'm guessing Ruzhyo, or his friend Fermbiz, is probably causing some trouble somewhere for somebody by posting the entire Halo Multiplayer Guide from the IGNInsider service into the forum at HBO.
We won't be reproducing it here-- I'm not an IGNInsider, but I'm betting there's probably something in their little agreement thingy that makes you promise you won't post their stuff elsewhere, otherwise nobody would ever pay for it.
However, there are a couple of notable facts in the post that I'll gloss over in the interest of fair comment. First of all, Halo has 13 multiplayer maps, some of which have up to 26 different game variations. The entire text of Part One includes level names and descriptions. Unfortunately, most of them lack the same style and panache that Marathon levels had. A long walk down a short hall... comes closest, which the IGN article describes as skinnier than a casting call for Ally McBeal.
