Since the Ultimate Doom leaderboard has been destroyed i was wondering if there is any way of having a NoMo run on Unity Ports...

Unity does not have a no monsters feature, unfortunately.

do you think it could be possible to create a nomo wad for unity and inject it like done with some other wads in the category extensions?

No, because;

1. it's frowned upon to edit an iWAD.

2. Opens the door for people asking for 1000+ other WAD's

3. The 2 WAD's we have that aren't officially on the Unity port, one of which just being a 11 map remake of the other one, are WAD's made by members of the Console Doom Community, which makes it a special case.

I've brought this one up in the past once before to other moderators. It was unanimously rejected.

EDIT: Meant 11 maps. Not 7.

alright then, thought it was worth a try. i guess no more NoMo for me then. i know it's not an "important" category but im also not gonna switch to DSDA/Doomworld cause of that category i think ¯_(ツ)_/¯

Don't blame you. Check out PSYDoom. It's Playstation Doom ported to PC, and it does have Nomo.

Not exactly classic doom but it's neat af.

thanks i'm gonna check it out
