Doom + Mario. Feels like this mod was made for me.

Since people seem interested in this, here is a download link. I'm also running this with the Mario sprites mod which is how I got the custom Mario guns and enemies, otherwise it's just Doom sprites.

have you tried doom the golden souls 1 & 2 ? it's almost like a mario fps

I've heard Golden Souls is excellent. I really need to play these!

Decent, way better than Doom.

Marioom

I do want to play this!

Here is the link

Soooo cool, take a look at Yoshis Safari for SNES for some cool ideas!

We’ve gone too far again. Lol

I wished the gun were a Zapper or Super Scope

The chaingun is actually a super scope in this mod
