Empeze a leer este tipo de historias y me han gustado demasiado,así que, porque no hacer una propia?

Un día llegué tarde del trabajo y me encontré a una misteriosa mujer en la puerta. Tras un momento de debilidad, decidí dejarla pasar la noche. Después de eso mi vida cambió para siempre. ¡¿Cómo iba a saber que la mujer que acogí era un acorazado?!

Rook, a max-level veteran of the FPS/milsim game QRF (Quick Response Force), has survived every map, every raid, every nightmare patch the devs have unleashed. Zombies, militias, quarantined islands-he's beaten them all. But during the new update Operation Cold Tide, something happens mid-evac. His SH-60 helicopter glitches mid-flight. He crashes in a forest he doesn't recognize. He feels pain-real pain. His HUD is gone. His weapons are real. And the world around him is not the game anymore. Now trapped in a medieval, pre-renaissance fantasy world filled with magic, monsters, kingdoms, and politics, Rook must survive using nothing but his modern gear, experience, and instincts. No respawns. No safe zones. No NPC backup. Just a gamer... ...thrown into a world that runs on steel and sorcery. Can a top-rank FPS operator survive a world powered by magic? Or will this new reality be his final mission?

Este es un fanfic de que hubiera pasado si en vez de Japón fuera Rusia el que pasa la puerta Teniendo un tono más realista

Original story by: 제피랜더스 (https://novelpia.com/novel/197572) For some, it's an ordinary day and an ordinary story, for others, it's a miraculous day and a miraculous story.

Individuals from all over space-time have gathered in one place. What brought them here? ... To watch movies, of course!

Well, I've finally decided to show what I've been up to all this time. This is another version, based on my main work on multiverse reactions. It differs significantly from the first versions, and you'll easily understand why when you read it. I planned to add chapters from this to the main one, but then changed my mind, thinking it might cause confusion. So I decided to create a separate fanfic. Read it at your leisure.

In 1997, a Gate appeared in Tokyo Ginza. From it, came the armies of Saderan Empire with the intention of conquest of Japan. But little did the invaders knowned, is that they've bite off more, than they can chew: the newly formed Allied Nations Force strikes back at the invaders and pushes the war into the world beyond the Gate. Meanwhile, the Gods are playing their own games, which will effect both of these worlds. It's magic vs technology, modern army vs mystical creatures and middle-age armies, cultures of the 20th century vs the culture of the middle-age society. The G.I. Joe are facing their first great challenge outside their own world.

The story begins in the midst of a brutal interstellar conflict known as Galactic World War VII. Tony Towson, a skilled soldier from the Pantheruos race, and Yemeni, his ally and eventual love, navigate the chaos of war. This fanfic is mostly inspired by Wolves That Walk Alone by TheManThatWalksTheAbyss115
