They hunt us. They bomb our worlds for target practice. A star cluster in the constellation of Orion rotates once every 1,000 years. Those who rule there have an ancient tradition: When each cycle ends, they train their fleets by spilling the blood of lesser beings. The enemy fleets are coming again. In response, the Rebel Worlds gather their starships to face the terrifying threat, and this time humanity is asked to stand with them. The last time they considered Earth, Vikings in longboats were raiding English coastlines. Today, we're less primitive. Today, we're a target.

Kyle Riggs is snatched by an alien spacecraft sometime after midnight. The ship is testing everyone it catches and murdering the weak. The good news is that Kyle keeps passing tests and staying alive. The bad news is the aliens who sent this ship are the nicest ones out there.

Soon, the portal opens and unleashes a storm of unbridled fury upon humanity.

It was a day like any other when suddenly the world changed. The universe reached a threshold humanity didn’t even know existed, and it was time to finally be integrated into the vast multiverse. A place where power is the only thing anyone can truly rely on.

One starship will either save Earth or destroy her. A century ago our star erupted, destroying Earth's wormhole network and closing off trade with her colonized planets. After being out of contact with the younger worlds for so many years, humanity is shocked when a huge ship appears at the edge of the solar system. Our outdated navy investigates, both curious and fearful. What they learn from the massive vessel shocks the planet.

For centuries, mankind has searched for nonhuman civilizations in the cosmos. These lost alien societies have finally been discovered—but they were destroyed long ago. Devin Starn starts off as a lowly rock rat aboard Borag, a mining ship working the dangerous end of the asteroid belt. Slowly, he gains prestige and purpose. When an alien base is uncovered, however, he must risk everything to protect his ship and her crew. What wiped out all the civilizations that came before humanity?

The Hundred Worlds have withstood invasion by the relentless Hok for decades. The human worlds are strong, but the Hok have the resources of a thousand planets behind them, and their fleets attack in endless waves.

Assault Captain Derek Straker is one such man among many.

Get ready to experience two more origin stories in the Backyard Starship universe.

When humanity reaches for the stars, our probes are destroyed. They crash into an incredibly advanced piece of technology: a massive force-field. Unknown beings have placed a barrier around our star and planets, enclosing us within. We’re locked inside a Great Sphere. Was this invisible obstacle built to imprison us - or to protect us? No one knows the truth, but it soon becomes clear the barrier has leaks. Aliens infiltrate and try to sabotage our efforts to escape our cage.

In the 25th century, humans have conquered space. The advent of faster-than-light travel has opened up hundreds of habitable planets for colonization, and humans have exploited the virtually limitless space and resources for hundreds of years with impunity. So complacent have they become with the overabundance that armed conflict is a thing of the past, and their machines of war are obsolete and decrepit. What would happen if they were suddenly threatened by a terrifying new enemy?

Two centuries after humanity colonized the stars, new dangers emerge. The peaceful inhabitants of the Conclave are threatened by expanding alien powers. Invaders threaten the star cluster, attacking our fringe settlements. Captain Bill Gorman has mysteriously disappeared. His clone, set aside for a dark day like this, awakens and begins to put together the pieces. What’s gone wrong out on the frontier? Why are our colonies being attacked by aliens while the Conclave worlds dream of better days? And what happened to the original Captain Gorman?

We were fighting on the wrong side of a war we couldn't win. And that was the good news. The Ruhar hit us on Columbus Day. There we were, innocently drifting along the cosmos on our little blue marble, like the native Americans in 1492. Over the horizon come ships of a technologically advanced, aggressive culture, and BAM! There go the good old days, when humans only got killed by each other. So, Columbus Day. It fits. When the morning sky twinkled again, this time with Kristang starships jumping in to hammer the Ruhar, we thought we were saved.

The year is 2108, and the North American Commonwealth is bursting at the seams. For welfare rats like Andrew Grayson, there are only two ways out of the crime-ridden and filthy welfare tenements: You can hope to win the lottery and draw a ticket on a colony ship settling off-world...or you can join the service. With the colony lottery a pipe dream, Andrew chooses to enlist in the armed forces for a shot at real food, a retirement bonus, and maybe a ticket off Earth.

Left to die on a volcanic world by the Skrull, McGill and his mercenaries face waves of missile attacks with nowhere to hide. When the Skrull seal themselves inside an impenetrable energy dome, McGill knows he has to get creative. Even if that means sabotaging alien power plants, blackmailing his superior officers, and using his own troops as bait in a deadly game of cat and mouse.

Jason Burke was a man hiding from himself in a small cabin high in the American Rocky Mountains when his simple, quiet life was shattered one night by what he first assumed was an aviation mishap. But when he investigates the crash, what he finds will yank him out of his self-imposed exile and thrust him into a world he could have never imagined.

The Confederation has fought three wars against the forces of the totalitarian Union. Three generations of its warriors have gone off to war, held the line against the larger, more powerful enemy. Now the fourth conflict is imminent, and the Confederation's navy is on alert, positioned behind the frontier, waiting for the attack it knows is coming.

When the Ornu came, they took Earth in a single night. Humanity never stood a chance. Now, they force us to crew their ships and fight their wars for them. They hold Earth hostage, and if we refuse to do their bidding, they’ll lay waste to our precious blue marble. Slaughtering the billions who live there. But when Captain Bill Henderson is sent to claim a small moon for his masters, he finds something they never accounted for. An ancient warship – a behemoth abandoned for millennia by a species that reached its peak at the dawn of the universe.

The colony on Haven-7 has gone rogue. The colonists have split into two factions: the Techborn and the Dusters. The Techborn have always ruled the planet. They control the remnants of the crashed starship that brought humanity to this new world. The Dusters… they eat Techborn dust. Now, the Techborn strength is waning. Their weapons are getting old, and radiation leaks from the aging reactors have created mutations. Some of these, like their brutish troops known as Tuskers, have proven useful—but others are abominations.

The year is 2650. Seventy-five years ago, an alien fleet attacked Earth. Without warning. Without mercy. We were not prepared. Hundreds of millions perished. Dozens of cities burned. We nearly lost everything. Then the aliens abruptly left. We rebuilt. We armed ourselves. We swore: never again. But the aliens never came back. Until now. With overwhelming force the aliens have returned, striking deep into our territory, sending Earth into a panic.

The Amazon rainforest holds a world-changing secret—a ship lost to time from another world. College student Will Kaufman unearthed the biggest archaeological discovery in human history… he just needs to find a way back to Earth to tell people about it. Four thousand years ago, a Federation bounty hunter Void ship crashed on a remote and primitive planet. There it remained until Will found it and accidentally reactivated it, launching him light-years away.
