Kristian Käll went on to major acclaim for his Legacy PWADs - Phobia, Ni'mRoD: IXNAY on the HOMBRE, and Phobia: The Age - and more recently his Heretic and Hexen projects, Curse of D'sparil and Curse of the Lost Gods. The first two happened during his tenure as a member of Unholy Software and their earliest release was a total conversion for the original Doom, published in 1998. Codename HYENA: Killer Machine gets mentioned every now and then but there's a hint of uncertainty behind the namedrops. It replaces the first three episodes of the original Doom - the last a decidedly Deathmatch dalliance - and has a fair bit of DeHackEd work in order to tweak the values of its core gameplay for a fairly different experience.
