After World War I, over 70 German ships interned at the British naval base Scapa Flow mysteriously disappeared... More than two decades later in 1940, the world is engulfed in a new war against the Mundus Empire, an invading force from another dimension. Having conquered the Southern Hemisphere and steadily expanding its territory, the Mundus Empire has finally set its sights on the Northern Hemisphere. The United States Pacific Fleet is annihilated off the coast of Hawaii, and the Imperial Japanese Navy's vaunted Combined Fleet suffers a crushing defeat at the hands of the Mundus Empire's fleet that has invaded the Truk Islands. Cornered, the Combined Fleet is relieved by the arrival of a secret fleet of battleships and warships that were supposed to have been sunk as targets under the Washington Naval Treaty, including the battleship Tosa and the German ships that scuttled themselves at Scapa Flow. Resurrected and transformed by the Magitek Research Department, these ships and weapons are Japan's new hope against the otherworldly invaders. Rise, scuttled fleet! RELEASE: 2022 (TL INCOMPLETE)

In the middle of the devastating Human-Covenant War, two child soldiers are meant to die for humanity. Instead, they fall into another world. When a stealth SPARTAN-III Program transport carrying young Spartans is ripped apart by a mysterious slipspace anomaly, only Tom-B292 and Lucy-B091 survive the crash. Stranded far from the war they were trained to fight, they awaken on the alien moon Pandora-a living world where the forests glow, the wildlife hunts back, and the Na'vi people live in harmony with the planetary consciousness known as Eywa. Raised as expendable weapons, Tom and Lucy know only orders, survival, and war. But Pandora is not the battlefield they expected. As the two Spartans struggle to survive in an unfamiliar jungle, they encounter a Na'vi hunting clan who see them as strange "sky demons" clad in metal. Yet compassion from a young hunter changes everything, giving the lost soldiers their first chance at something they've never known before: family. But peace won't last. Human forces from the Resources Development Administration arrive, carving into Pandora's sacred lands in search of wealth. Caught between the species they were born to protect and the people who saved their lives, Tom and Lucy must make an impossible choice. Will they remain humanity's weapons... Or become defenders of a world that taught them how to live? Exiles of Two Worlds is a crossover epic blending the brutal military tragedy of Halo with the spiritual wonder of Avatar-a story about survival, healing, and two lost Spartans discovering where they truly belong.

An alien invasion of Earth is a common trope in science fiction. Some of the aliens visiting our planet might just see it as a nice vacation spot. Others might be refugees from a distant war. Or they come as predators, ready to exploit the planet or enslave its inhabitants. Welcome back to volume 2 of alien invasion stories!

When the Andromeda Initiative's journey through the stars is derailed by a catastrophic temporal rift, Lieutenant Cora Harper finds herself falling-not onto a golden world, but back to an Earth she never knew. It is a planet scarred by nuclear fire, reclaimed by the fierce warriors of the Thirteen Clans, and haunted by the high-tech ghosts of the Mount Weather bunkers. Crashed in the heart of the Trikru territory, Cora is rescued by Bellamy Blake, the protective leader of a group of exiled delinquents known as The 100. While the Ark descends from the sky and the Grounders sharpen their blades, a much darker threat emerges: the Kett, a relentless alien species that has followed Cora through the rift to "Exalt" the survivors of Earth. Bound by a reluctant alliance and a slow-burning attraction that defies their different worlds, Cora and Bellamy must bridge the gap between advanced technology and primal survival. From the glowing Jardaan Vaults beneath the soil to the political shadows of Polis, they are the only ones who can unite the Sky-People and the Grounders against a biological apocalypse. The stars brought her here, but the Ground will define her. In a world where the past and the future have collided, they aren't just fighting for a home-they are fighting to prove that humanity is worth saving.

When a mysterious crimson rift tears Ruby Rose from Remnant, she crash-lands in a dying New York City-one drowning in alien infestation, corporate betrayal, and a virus that's turning humanity against itself. Moments before his death, a legendary soldier known as Prophet chooses Ruby as the successor to the Nanosuit 2.0, a weapon designed to fight an impossible war. The suit bonds with her Aura, amplifying her speed, strength, and Silver Eyes into something the alien Ceph have never faced before. But power alone won't save Manhattan. Stranded in a world without her team, Ruby is forced into an uneasy partnership with battle-hardened Marine James "Alcatraz" Rodriguez. He sees her as a reckless kid in overpowered armor. She sees him as a gruff soldier who's forgotten what hope looks like. Yet as the city burns and the Ceph close in, their alliance becomes something more-a bond forged in gunfire, sacrifice, and shared loss. Through collapsing skyscrapers, underground alien hives, and the heart of Central Park's final battlefield, Ruby must decide what kind of hero she'll be in a world that doesn't believe in them anymore. And as the war reaches its devastating climax, she'll learn that sometimes family isn't the one you're born with- It's the one who stands beside you when everything else falls apart. A high-octane RWBY x Crysis 2 isekai retelling filled with brutal urban warfare, emotional sibling bonds, alien horror, and the enduring light of hope in the darkest battlefield.

When the Forward Unto Dawn was torn in half, the Master Chief didn't just bring a fragmented AI to the Forerunner world of Requiem-he brought the shadows of an ancient world. Bela, Cassandra, and Daniela Dimitrescu were born from the nightmare of a Romanian village, bound to a biological rot that made them monsters.

As they face the Didact's wrath and Cortana's betrayal, they must confront a chilling truth: their "stagnant" blood is the only thing the Forerunner machines cannot control.In a galaxy of cold metal and digital gods, the survival of humanity may just depend on the daughters of the dragon.

On the fortress world of Reach, Spartan-B320-known to her team as Kat-is a master of logic, encryption, and cold tactical reality. But when a classified ONI artifact shatters during a Covenant raid, Kat becomes the host to something that defies every law of UNSC physics. It is ancient, hungry, and relentlessly feminine. It is a parasite. It is a partner. It is Venom. As the Covenant's holy war begins to rain plasma down upon the colonies, Kat finds herself fighting a dual battle: one against the overwhelming alien armada, and one within the confines of her own MJOLNIR armor. The symbiote doesn't just offer enhanced strength and impossible regeneration-it offers an intoxicating, possessive intimacy that threatens to consume Kat's humanity. Amidst the smoke of New Alexandria and the frantic defense of Sword Base, a dark romance ignites between the Spartan and the "She" within. As Noble Team falls one by one, Kat must decide if her loyalty lies with the dying command of the UNSC, or with the alien entity that promises they will survive the end of the world together. The Fall of Reach is inevitable. But with the Symbiont's reach, the tragedy will be written in blood, black ichor, and a love that refuses to die.
