REKKR is a full four-episode total conversion for the Ultimate Doom set in a faux-norse/celtic fantasy world overrun by monsters. Made within vanilla limits and assistance of DeHackEd.

A short wad with a small branching path and a custom plasma rifle.

Requires cc4-tex to play which you can get here.

Early 1997 megawad with new monsters, altered monsters, tricks and traps and at least one puzzle.

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.
