Prepare for Goatse!

Hi, I’m ducon, aka ellisllk sometimes.

If you want Doom screenshots, see here but I have more than 4000 personal Doom screenshots on my hard disk so I created the map skel and wad skel to make them useful for someone.

Then maybe I’ll take care of Crusades, Inferno (by Christopher Lutz), Dawn of the dead, the first ten maps of DSV3war, Scythe, Castle of eternal carrots in the sky, Memento Mori II

Maybe you, dear reader, should add other information in the articles I created (monster count, secrets, tactics, automap, links…)
