Unique WADs

I am on a quest to play some unique wads be it unique strange or unique one of a kind i hope some of you can help me on my endeavours 

The sky may be, masterpiece if you ask me.

Off the top of my head, for various meanings of unique: TheGiven (and basically anything by Dobu Gabu Maru), AVJ, saltwater, Going Down, aboosysv, ESP, also check out https://doomwiki.org/wiki/Top_100_Most_Memorable_Maps

Null Space by Russell Pearson is very unique

Shrine by Scumhead. Visually very unique, haven't played it yet, though.

Ashes 2063 by Vostyok. Great looking total conversion with unique gameplay elements and an incredible soundtrack.

A Boy and his Barrel by Jimmy. Unique gameplay and funny premise.

The DBP’s are all unique wads. Cyb’s Freaky Colonoscopy is the first one that comes to mind!:

Even though it’s a joke wad, DO-TIMS is also undoubtedly unique: https://www.doomworld.com/idgames/levels/doom2/Ports/megawads/do-tims

Pirate Doom is probably my favorite single-player Doom experience this side of 2000: https://www.moddb.com/mods/pirate-doom

Golden Souls 2 is no doubt a unique mod, fusing what makes Doom and Mario great: https://www.moddb.com/mods/doom-the-golden-souls-2/downloads/doom-the-golden-souls-2-14

I ran a community project called Doomed in Space that was divisive among reviewers. It is most certainly a unique Dooming experience!: https://www.moddb.com/mods/doomed-in-space/downloads/doomed-in-space-final-version

There’s definitely way more out there.. thousands on idgames and even more on the greater net!

A Boy and his Barrel by Jimmy. Unique gameplay and funny premise.

This is tied with Doomguy Gets a Puppy for “cutest Doom wad of all time”. 

I'll agree with Doomkiddo and also reccomend the DBPs

Grezzo 2 is also unique, along with other less positive adjectives

    I am here to shill A.L.T., play it if you want a really surreal experience, a wad that takes the usual DooM conventions and throws them out of the window. Most of the maps have that Russian realism-but-uncanny-valley style.

Here comes some family-friendly stuff: (the latter is like Animal Crossing in Doom, by the way)

Well, my fav wad A.L.T was mentioned, but have you ever heard of this one:

Action Doom series

NoYe

La Tailor Girl:

Crapi (aka Crapirc5) is unique WAD too. Pseudo-open world with giant territories. I never saw any wad which tried to recreate the idea of Open World Quest WAD.

UNLOVED
 

My taste for unique wads might be invasion my favorite unique wad is

Futur war invasion

Futur war invasion

You can easily find this but here it is

Boss battles v17

Armageddon 2 v63

Armageddon 2 a very unique invasion mappack thats all I can think of 

While Ive beaten this twice and I cannot recommend it. Prodoomer V3 is rather unique I guess. Just remember its a commitment and will tax you mentally a lot

Thank you kind folk for the suggestions i now will have some stuff to pad the time wile in quarantine stay, safe my dudes
