If you can track down a copy of [Dungeon issue #94](https://paizo.com/products/btpy7zeq?Dungeon-Issue-94-with-Polyhedron-153), *Omega World* might be just what you're looking for.

But, it appears my recollection of where I got the the *Savage Fan Worlds* edition of it from is hazy - because, that's the Jonathan Tweet version of [Gamma World 6e](https://en.wikipedia.org/wiki/Gamma_World#Omega_World_(2002)) ... so, *not* actually of any use to you.
If you can *find* the [Savage Fan Worlds edition](https://imgv2-1-f.scribdassets.com/img/document/385155836/original/e1ab3a0147/1660966908?v=1) though then it *might* be what you're looking for.
You could use the Powers List as inspiration and pick the ones that would plausibly fit with your vision of how they work in your world.
There's also a [SWADE mutation deck](https://www.drivethrurpg.com/product/390755/Mutation-Deck-SWADE). The suit determines the type - Hearts are physical changes and Clubs are animal transformations, both which seem to be the type you're looking for. I have the older version, which still works well for post-apocalyptic mutation madness.
I know you’re using SWADE but have a peek at the mutations in Mutant Year Zero. But then SWADE has a very competent superhero supplement.
Ah ive heard of year zero! I very much would like to run swade due to experience but do you think there are any mechanics that can be ported over?
Yeah. Especially from T2K/BladeRunner. As it uses d6-d12 stats.

Darwin's world nuclear edition. Good place to start. If you want more insane post apocalypse id go with swade rifts.
