"the doom"

I'm glad it's for doom and not one of those crappy snapmap versions!

dope!

doom weapons, doom monsters

doom music? I'm not sure anymore.

this is not DOOM engine.

Dunno about the one in the video (or if it's the same), but the wad below runs in the original engine too:

looks like shit with all the mods

Missed 2 secrets?

is that jump sound from doom? :)

This is not the original Doom, i thought is obvious but i think this is Gzdoom or something similar.

Anyways, i'm not a big fan of brutal shit, but the map looks like meh to me.
