In the 20th century Earth sent probes, transmissions, and welcoming messages to the stars. Unfortunately, someone noticed. The Galactics arrived with their battle fleet in 2052. Rather than being exterminated under a barrage of hell-burners, Earth joined their vast Empire. Swearing allegiance to our distant alien overlords wasn't the only requirement for survival. We also had to have something of value to trade, something that neighboring planets would pay their hard-earned credits to buy. As most of the local worlds were too civilized to have a proper army, the only valuable service Earth could provide came in the form of soldiers....

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?

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.

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.

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?

Zac was alone in the middle of the forest when the world changed... The whole planet was introduced to the multiverse by an unfeeling System... or God. A universe where an endless number of races and civilizations fought for power and dominion. Zac finds himself stuck in the wilderness surrounded by deadly beasts, demons, and worse. Alone, lost and without answers, he must find the means to survive and get stronger in this new cut-throat reality.

My name is Kazimir Wolfe. People call me "Kaz", except they don’t. I never use my real name; it’s too dangerous, for me and for anyone I meet. I’m on the run from the law, who think I killed my aunt, and from whoever did kill her, because they want to finish the job. So, I move around a lot, working construction or whatever job I can find. It’s a lonely life. I don’t let anyone get close...people who get close to me end up dead. Why? I’m a wizard. The world’s only wizard, as far as I know.

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.

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.

More than two centuries after World War III poisoned the planet, the final bastion of humanity lives on massive airships circling the globe in search of a habitable area to call home. Aging and outdated, most of the ships plummeted back to Earth long ago. The only thing keeping the two surviving lifeboats in the sky are Hell Divers - men and women who risk their lives by skydiving to the surface to scavenge for parts the ships desperately need.

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?

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

Ten thousand years ago, a single alien super-ship survived a desperate battle. The vessel's dying crew set the AI on automatic to defend the smashed rubble of their planet. Legend has it the faithful ship continues to patrol the empty battlefield, obeying its last order throughout the lonely centuries.In the here and now, Earth needs a miracle. Out of the Beyond invade the New Men, stronger, faster and smarter than the old. Their superior warships and advanced technology destroy every fleet sent to stop them.

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 wilds of a jungle planet, the Legion fights in brutal combat as Republic marines fly their SLICS from one tragedy to the next. H292, a repurposed warbot, shows the heart of a hero as he wades into the battle not to destroy - but to save.
