This is quite amazing. I never grow tired of seeing what people in the Doom modding community are able to achieve.
Doom 4 Vanilla recently showed up, what the developer describes as "Doom 2016 the Way 1993 Did It" and it really does look like a huge amount of fun. It's not the work of a single person though, as it does pull in mods and resources from others all under one roof.
More about it:
After almost two years, I'm proud to announce my biggest project so far: It's a gameplay mod inspired by Doom 2016, made to be compatible with any source-port (or without any of them).
100% vanilla compatible and full of dehacked tricks! All under the limitations of the original Doom2.exe
If you do try it out, let us know your thoughts in the comments.
