Even more obscure is the GDX port of Witchaven, Capstone's fantasy-themed FPS/RPG. It's a bit like Hexen, although far jankier and vastly less forgiving. WitchavenGDX isn't complete yet, but you can find it and all the other GDX ports over on Makarov's page here.
You're getting two builds: patched (Enhanced) and retail (Original) for those of you who prefer an unaltered experience as a bonus. Both builds are running on DOSBox with a custom configuration tool. The Enhanced build features fixes introduced in EGwhaven, a must-have community project, which addresses an array of bugs and issues with the game (we'd like to thank ETTiNGRiNDER for the contribution to this release). Additionally, the controls are re-mapped to what you'd expect to see as a default in a first-person game nowadays.
