I can, however, justify how extra crappy it is, if you allow me to explain myself with this fancy story:
A lightning strike left me without internet for a bit over a week. So, the incredible boredom, terrible weather and floods made me stay at home. I then had a brilliant idea, and though "Hey! Let's put squids in a serious game." and started making a Splatoon mod for Doom because my life needed squid fights reasons. I had made some first person views of several weapons just for giggles in Garry's Mod (as at the time there were no models avaible for XNALara, which I use the most and greatly prefer over GMod). Of course, I used that. Naturally, that means that the guns' animations are actually just the same single frame moved around in a terribly sloppy manner to simulate something actually happening. Why didn't I make more frames? Because I didn't have internet, and I have Garry's Mod as a shared game, so I can't play it without 'net since I technically don't own the game. I had also a limited supply of assets, mostly I had made on my own with GMod, but without the 'net I couldn't get more. I did have a few songs though, luckily. Of course, without internet I couldn't read guides, ask for info or read the wiki to have a slight clue on how to do something actually useful, but I had fun making this, and that's that.
So!
I hereby present you the most sloppy mod ever: A Splatoon themed mod that's nothing but a main menu change, a few weapons terribly "animated" which replace the existing Doom weapons' sprites, a few songs and absolutely nothing more because I didn't have enough to work with and no access to info on how to git gud.
Spoiler:I even made a logo! It is truly a work of art:

Spoiler:I took some screenshots so you can fondly regard horror:
Spoiler:And here is the largely relevant list of weapon replacements, in case you actually care:
Spoiler:I can now make better sprites with actual animations, but I kind of deeply regret using arms. I think I'll update it to be armless, to have a Goldeneye-like feel, which I am personally deeply fond of. That, a few sound changes, maybe a few more songs, but that's about as far as my knowledge takes me for now. So, if anyone actually cares about the thing, grab it and do what you wish with it.
So, finally, I give you the download:
