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.
