Sverre Kvernmo (if you don't know who he is, go away... ok fine, mapper for Eternal Doom, Redneck Rampage, Daikatana, and KISS: Psycho Circus) sent word that BjoernarJohansen, an old friend of his, has released a couple of never-before-seen Doom 2 maps over on his homepage. They... eh, I'll just paste in what Sverre sent me.
We used to collaborate a lot back then and the maps would have been included in the Cabal 32-map set if that project had ever been completed, but that never happened so the guy never released them anywhere! Anyway, if I remember right they're crazy difficult (Malcolm Sailor/Cabal-style) so they should be worth the time of anyone out there still counting their bullets and digging the old-school map-style.
The screenshots don't look half bad either. Check them out.
