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. This new version comes bundled with GZDoom, but is still playable with other ports if the user desires, and prominently features one canonical fourth episode to conclude the story, replacing the bonus maps from the original release. 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. On January 1, 2023, a new add-on was added to the commercial version, VR-3KKR, featuring nine challenge maps in the E6 slots.
