Rekkr

Rekkr is a 4-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.
