REKKR

REKKR is a four-episode total conversion, created by Matthew Little (Revae), with a full soundtrack created by Tom Jensen (HexenMapper), sound effects provided by TerminusEst13, additional textures by Chris Kassap (lupinx-Kassman), and additional mapping by Angry Saint, Brayden Hart (AD_79), Bzzrak Ktazzz, Chris Kassap, James Paddock (Jimmy), Jaws in Space, SuperCupcakeTactics, TerminusEst13, and Velcrosasquatch. The mod is distributed as both a PWAD for Ultimate Doom (or Freedoom; since all content is replaced, it does not matter which one) and a stand-alone IWAD version.

Announced in September 2016, the mod was first released on July 10, 2018 and received its last update (v1.16a) on August 20, 2019. On September 22, 2020, REKKR became the first TC to join the lineup of official add-ons for the 2019 re-release of Doom. On October 11, 2021, REKKR was released on Steam as REKKR: Sunken Land, featuring one canonical fourth episode, which replaced the bonus maps. On December 22, 2021, REKKR was also made available on ZOOM Platform as REKKR: Sunken Land - Super Digital Deluxe Edition, bundled with its soundtrack in FLAC format.

Story
You're a rekkr, a viking warrior. Your kingdom is at war against a superior foe. As you return home after a failed expedition, your ship gets wrecked some distance from the shore. As you swim, you notice something is wrong: has the enemy come here while you were away? Except it doesn't look like it's occupied by a human army...

The rest is told as you go through the levels, and in the text screens at the end of the first three episodes. (The original fourth episode consists of bonus levels and is not part of the story.)

Standalone DOS version
On February 8, 2022 UDoom32 author OpenRift released a standalone version of REKKR for. It utilizes a custom executable called which unlike the official executable, embeds the DeHacked patch, but it is also a executable hack where it includes REKKR's custom quit messages found in the  lump, edits all Doom-equivalent strings in the executable to say REKKR instead, and includes custom par times found in the MAPINFO lump.

The standalone version also includes:
 * : A hex-edited version of SERSETUP.EXE, designed to launch the aforementioned
 * : Like, but for the.
 * : A version of DeathManager! version 1.1, edited to read and write from {{{c|DM.CFG}} respectively
 * : A hex-edited version of Chex Quest's Setup program with names changed
 * DeHacked: Comes with a custom INI file to specify the new executable and WAD names
 * : A tool that disables vertical mouse movement. The batch menu used by DOSBox is configured to run this automatically
 * DOSBox Staging v0.78.1: This is included for convenient play with a batch menu with shortcuts, akin to GOG's DOS game installations

REKKR: Sunken Land also has its own executable called, but due to the current state of the Sunken Land IWAD, it requires the Ultimate Doom IWAD to function and is thus not a standalone game.
