Summary
Once a dweller of Vault 11, Overseer Tyler Joseph now faces the harsh realities of the Mohave wasteland. Outside the vault, on the cracked and nearly deserted highway, he crosses paths with Josh Dun, a mysterious raider, hardened by violence, who holds onto a dark past.
Survival blinds them at first, but even in a brutal world scorched by war, something deeper still dares to burn. Together, they brave the dangers of the desert, uncovering Vault-Tec's lies, and discovering a love that cuts deeper than a blade.
AKA my autism slop.

No Place Like Home by Thunderstorm_of_Destruction94

Summary
Before the bombs fell, Katherine Witherspoon was a nurse living a fairly ordinary suburban life with her husband and son. That all changed one October day when someone pressed The Red Button and the entire world came to a screeching halt. Now, 200 years displaced, she has to learn how to live in a world where all the rules have changed. When the wasteland has chewed her up and spit her out, can she learn to forgive the very people that hurt her the most?
A story you know, with a few new elements twisted in. A reimagining of the Fallout 4 storyline, told through the eyes of a woman just trying to pull her life back together. A slow burn, Kat starts to learn that Home isn’t the place, but the people you have in your corner.
I tried to write this in such a way that it could be enjoyed by anyone—even if they don’t have any experience with the Fallout series. If you like grounded, character-driven, post-apocalyptic stories with some mild sci-fi elements, I think you’ll find something you like.

Summary
In most universes, the Gates opened in low orbit above Pluto, others to their equivalent, leading to a shared dimension connecting all of them together. For the worst, as it would seem, as the Imperium of Man uses this new beachhead to launch invasions into every sci-fi and fantasy universe one could imagine.
Welcome to the Janus Chronicles. Where we will explore ever possibility that comes with this premise. And if you have any suggestions on what crossover event should happen, or what characters should meet, please let me know, and I will see if I can incorporate your idea into the story.

Could civilization be saved if a Nuke occurred?

Summary
The terminal monitor swings, filling Shadowheart's vision with the gentle chyron of Mother Mainframe. Upon the screen she is two perfect lips and a gaze covered by a fluffy eyemask. There’s a fetching pair of eyes embroidered upon its silk: lined dark, full-lashed and painted deep purple. They stare out with a knowing gaze while Mother, ever-working through each vein of their Vault, slumbers softly beneath.
The face soon fades. For a moment, she is alone in the false moonlight of the medbay, before the ominous tick-tack of text spills out in stark green.
>Hello, citizen SHADOWHEART. Welcome to your Vault-Tech Certified Check-Up! Don't recall the last one? Congratulations– it worked!

Summary
A realidade das Vaults era um luxo, lidar com a radiação e com o mundo lá fora não era o que as pessoas estavam querendo para a sua vida, muitas se viravam como podiam, Eren aprendeu desde cedo que ser um caçador de recompensa poderia compensar bem mais para sua sobrevivência.
Mikasa, por outro lado, vinha de uma Vault esquisita até mesmo para os padrões das demais. A vault 123 era completamente fora da realidade. Tinham um sistema próprio e lidavam com tudo de uma maneira que parecia sair de um conto de terror psicológico.
Seus caminhos acabaram se cruzando quando Eren recebeu uma proposta tentadora: dez mil caps pelo sequestro de Mikasa Arckerman com vida.- Language:
