Project Atlas (Isekai)

-This year, Atlas Corporation discovered an old portal, a very large portal that was deployed in an urban location. This portal will be useful because "Atlas," besides being a company, is part of a US resistance against Russia, which in recent years had already invaded parts of North and South America. This is good because resources in the country are scarce.

-Japan also discovered a portal, and the Japanese evacuated their entire country, in order not to help their neighboring countries against the potential enemy (i.e., Russia), and escaped through that portal. Now only the United States portal remains.

-A team, {{user}}'s team, was deployed to verify the area and also to establish a new base for the remaining survivors from the United States.

-In short, upon crossing the portal there is another dimension. This dimension is teeming with extraordinary creatures, and the thing is that this dimension is medieval, but Japan, or rather the Japanese, are somewhere in this dimension, although their location is unknown....

-It's the largest company in tactical and military technology, boasting a vast array of devices, weapons, suits, vehicles, robots, and gadgets for soldiers.

-Soldiers always wear exoskeletons to increase their strength, speed, and ultimately their physical and mental capabilities.

-One is in the year 2045; this dimension is high-tech, or one could say a very distant future where technology is very advanced.

-The other is a medieval isekai world; the technology isn't advanced at all, but there is magic and all kinds of creatures.

The creatures are a diverse bunch with different races, cultures, and languages;
-humans
-Goblins
-Elves
-orcs
-werewolf
-fairies
-demons
-succubi
-golems
-dragons
-dwarfs
-slimes
-Hydras
-fairies
-Harpies
-sirens
-snake men
-Nekos (female version only)
-Cow women
-Humanoid fungi [they look like humans but only have 4 fingers and are 2 meters tall]

-Tero-pluridatics or Birds of Prey [creatures that are like a velociraptor but with feathers and can fly; these can commonly be domesticated and are often seen with clans of elves, humanoid fungi, and some humans]

(Each of these creatures has a female variant, and some are very common in certain kingdoms or habitats with large human populations, or conversely, with small human populations.)

Here there are only things that are already military or not very creative;
-Robots
-Drones
-The soldiers are wearing exoskeletons.
-High-armored vehicles and long-range weapons

Here there aren't only allies, there are enemies:

-The Japanese are one; they already created a civilization in the medieval world and are far removed from the Atlas company and its people.

-The Russians aren't in the medieval world, but some rebel groups entered the medieval world.

-Many of these species have their own particular languages, but all languages have a purpose.
Understanding between species and even with humans, each language is different with new words and meanings.

-The landscapes vary, from being large forests with trees 130 meters tall (which serve to establish villages and tree houses in them), caves of giant mushrooms, desolate or populated deserts, swamps full of humidity and rain, and normal plains or those with flowers.

There are all kinds of landscapes, even strange ones.

Climates vary between rain, hail, tornadoes, hurricanes, sunny days, or drought days.
