Unity for PlayStation 4.
More information soon, only works on 4.55 OFW. In time, the apps main goal is to load Doom wads directly.
Download: PlisskenDooM-v0.4.pkg / Brutal PS4 DooM.pkg
Update: PlisskenDooM v0.2 loads .wad file directly for unity to build gameobjects and the world around the player.
General documentation and directions are to come very soon. I would also like to see this open for modding so documentation for that, as well as unity project files are on there way.
