A classic TC released in 1999 by Chilean doomers-turned-developers
ACE Team, loosely based on the
Batman: Knightfall story arc. Features 32 maps spread out over 7 chapters (with some fairly fancy mapping work by '99 standards), with new weapons, enemies, and bosses by way of DeHackEd, plus a great custom soundtrack.
The first download is a version specifically updated to work with
Crispy Doom, so please use that source port when playing it. The second is a patch for use with
ZDoom and
GZDoom only, and the .zip includes the original WAD and DEH so that you don't need to download them separately.
