A science-fantasy crossover, that asks "What If the World of Arknights met the 21st Century United States." Beneath the classified depths of Area 51, a decades-long black project known as Project ARKSEK has achieved what was once thought impossible: the creation of a stable, functional gateway to another world. In the wake of this discovery, the United States mobilizes its most advanced and sophisticated military units and scientific minds to establish the first Human presence beyond the Gate. However, this new world known as "Terra" by its inhabitants is no empty frontier. It is a world shaped by its own complex History, Societies, Nations, Geopolitics, and scarred by Catastrophes. Home to diverse nations built upon the foundation of Originium, an enigmatic energy rich mineral that fuels entire civilizations, but also spreads a deadly disease that has no cure, known as Oripathy. What begins as an exploration mission slowly becomes something far more what the US could have ever bargained for in another world. Fraught with discoveries and dangers unlike anything humanity has ever encountered before. As American forces attempt to understand and navigate this alien yet familiar landscape, they will be forced to confront questions of Morality, Control, Diplomacy and weighing the cost of Intervention. What they will find on the other side may change the future of both worlds. For better or for worse. Every discovery always has a cost. And some doors, once opened, cannot be closed.

Beneath the snow-capped Ural Mountains lies an old Soviet bunker long abandoned by its creators. On the edge of Sangvis Ferri territory, Griffin & Kryuger must secure this front with the help of their newest employee, Commander Zeldri. Zeldri must gather supplies and build up his forces to secure the sector as a new threat looms on the horizon. But, the Mountain is not without secrets of its own. What lies behind doors frozen by time and forgotten by those who closed them? Shall we open them? Wake up, Commander, you're screaming again.

Most commanders in G&K go through the commanders course before being stationed to a sector. Aiden Cross, the developer of the T-Doll Taurus .38, is finally enlisted into it. Will he be able to handle three years of rigorous training, or get kicked out of course and lose his opportunity to be a commander and get Taurus back?

Augmented supersoldiers. Pilot. You were one of them, codenamed "Mantis". You thought of the mercenary group "Six-Four" as your family, and they thought the same of you. Even if you're the youngest of the bunch, you had the skills to back it up. Giant bipedal mechs. Titan. Originally created for civilian use but repurposed as a war machine. Yours were a Vanguard-class titan, named "Falcon". A bond between a pilot and their titan is something special. You're incomplete without your titan, and so is your titan without you. A mission that went wrong sent you and your partner to a far-flung place. A place that is filled with... angels? With a shotgun? Kivotos is standing by for Titanfall, Pilot.

Having lost his unit in a gruesome war that's still fresh in his mind, Palus Viotto, a young mercenary makes a desperate dive into an unknown world. Kivotos, a deceptively utopic city garnering advanced technology and academies of varying origins and customs. Surrounding it reminisces of abandoned ruins remain veiled in an unsettling amount of warm and cool hues, radiating from its firearm-wielding inhabitants. Out of place, out of time, with no way back, and an unfamiliar voice requesting his help. This torn contractor alongside his ragtag crew, dives forward into strange and unfamiliar territory in a world with new challenges far different from what they were accustomed to.
