In 2017, an expansion pack to Skulldash, entitled Skulldash: Expanded Edition was released, allowing the mod to be played in GZDoom, and featuring an additional eighteen levels created by O'Sullivan and various mappers from across the Doom community. The mod is intended to be played using the OpenGL renderer, with the effects of the software renderer ranging from sub-optimal visuals to major graphical glitches on some maps.
