Creaphis (wad compiler), ArmouredBlood, The Green Herring, Enjay, TimeOfDeath, LogicDeluxe, Nuxius,
A bit more than an episode's worth of recreations of Doom's e1m1, "Hanger", all of which were made entirely from memory. There isn't much new gameplay here, or stunning new visuals, but if you think it might be interesting to see what different Doom community members can remember about the map where It All Started, then... check this out!

Yes, many, most of which were left intact due to the nature of this experiment. There's some tutti-frutti when playing on vanilla, but no VPO's.
