About the Game

Choose from 20+ distinct superpowers! Lead your team of superheroes to the moon and beyond, and stop the supervillains of PSION—unless, of course, you join them.

Posthuman: Guardians vs PSION is an interactive superhero novel by Evan J. Peterson, author of Drag Star!, where your choices control the story. It's entirely text-based, 300,000 words and hundreds of choices, without graphics or sound effects, and fueled by the vast, unstoppable power of your imagination. 

Decades ago, legendary hero Adam Atom created the Guardians: an elite force of posthumans to protect the world from those who use their powers for harm. In response, PSION—the Posthuman Supremacy International Organized Network—sprang up. The United Nations calls them terrorists; they call themselves a liberation army protecting posthumans from human persecution.

Now PSION is hatching their most ambitious plan yet—and it's up to you and your fellow Guardians to stop them. Together with your team—super-genius Pi, teleporter Taikonaut, elementalist Moxie, healer Gilead, brilliant fighter Vogue, and Basilica (who can turn herself 20-feet tall and turn her skin to stone)—you'll travel to the moon, Mars, and all over the earth to try to unravel their plots. Why have your allies gone missing?  Where is PSION's new secret base? Why is their leader BrainSkull gathering such a vast amount of power—and what is he going to do with it? Is the next Posthuman War on the way?

Expand your powers, train new cadets to join the next generation of Guardians, and protect the world from PSION. But along the way, you might just discover that they're not the villains that everyone claims they are…

• Play as male, female, nonbinary, or agender; gay, straight, or bi; asexual and/or aromantic

• Choose from over 20 superpowers: shapeshifting, super-strength, telepathy, weather control, gravity-bending, technomancy, energy manipulation, and more! Then level up to expand your powers and discover new ones!

• Romance a supergenius with a tragic legacy; the class clown elementalist; an intense former vigilante healer; a friendly teleporter, or a stone-skinned rebellious new recruit. Or maybe you still carry a torch for your Academy classmate who switched sides…

• Travel the world gathering up new recruits for the Guardians—if PSION doesn't get to them first!

• Keep an eye on the public image of the Guardians! Field questions at press conferences, and make sure that you look great in the Planetary Bugle!

• Bend elements! Read minds! Smash stuff!

They say it takes fire to fight fire. You are the fire.
