10 Sectors (10SECTOR.WAD)

Way back when in the year 2000, while the rest of us were fighting off Y2K, Doomworld hosted a contest. The goal was to create a Boom map using no more than ten sectors. The idea has more merit than one might think at first, as - to quote DoomWiki - "[a] sector does not have to be a single polygon. For instance, two squares can be separate and non-contiguous, but still be part of the same sector." What this meant for 10 Sectors was a ton of maps that had a bunch of "sectors" that only had ten different combinations of ceiling and floor flat, height, light, tag, and type. A whopping 146 entries were submitted, and the cream of the crop were selected and deposited into this, the 10 Sectors megaWAD.

HACX: Twitch'n Kill (HACX.WAD)

HACX was never destined for greatness. A commercial TC published for Doom II in 1997 and featuring some of the better-known authors of Doom's golden age ('96-'97) (notably superstars Adelusion and Iikka Kernanen), it came out subsequent to the release of the new breed of FPS games, namely Quake and Duke Nukem 3D. It's odd, because HACX feels like a natural bridge between the Doom and BUILD engines. It has themed maps, destroyable objects, and a penchant for goofiness that lies outside the normal bounds of Doom. Unfortunately, it never fulfilled the proposed design documents, topping out at twenty-one out of thirty-two levels replaced, and that's looking at it from a purely numerical standpoint.
