"Watch monsters and demons you may have never seen before, enter the zoo, take a look at the Beastiary!" Yeah, after only a few days of work (yes yes, this looks almost like a Doom workaholic) I have finished the official Doom Beastiary, filled with over 60 custom monsters for ZDoom, GZDoom and Skulltag. Feel free to use them, don't forget to credit and maybe even contribute your very own monsters to this archiv. Lots of thx to all the contributers that already put their monsters for free use in the Monster Resource WAD some years ago!
[UPDATE] Added some descriptions to the monsters, thx to Doomshadow for these!
