The World of Earth-Prime

Earth-Prime is the setting of Green Ronin’s Mutants & Masterminds RPG. First detailed in the Freedom City sourcebook and receiving its ultimate expression in the Atlas of Earth-Prime, it is a four-color world of excitement and adventure. The greatest heroes of Earth-Prime are the Freedom League, who have been thwarting dastardly villains since the 1970s.

Meet the Heroes!

Bowman

For generations, Freedom City has always had a battling Bowman. The first Bowman, and his young ward Arrow, fought criminals and Nazis in the 1940s.The current Bowman, Fletcher Beaumont III, honed his skills as a member—and then leader—of the Claremont Academy’s Next-Gen team, before accepting an invitation to join the Freedom League following his graduation.

Captain Thunder

Test pilot Ray Gardener was transformed into the mighty Captain Thunder when a freak storm conjured by rogue scientist Dr. Stratos zapped his cockpit with lightning. Using his newfound powers of super-strength, invulnerability, flight, and electrical control, Captain Thunder brought Dr. Stratos to justice and became one of the world’s greatest heroes, the leader of an all-new Freedom League.

Daedalus

Scholar. Genius. Philanthropist. Inventor. The man known to the world as Daedalus is a legend hidden in plain sight, for he is, in fact, the mythological Daedalus, who designed the labyrinth to contain the Minotaur for King Minos. Daedalus wears a gravity-powered suit of armor of his own invention, and defies the schemes of Hades, the Olympian god who longs to finally claim the immortal inventor’s soul.

Dr. Metropolis

In the aftermath of the Terminus attack on Freedom City, rescue workers searching through the rubble saw a figure of concrete, steel, and glass rise up like a ghost, discarded cloth wrapping him like a hooded cloak. “I am Metropolis,” he intoned. “I wish to help.” Ever since, the mysterious master of metropolitan structures has been the self-appointed guardian of the city and its people and a stalwart, if stoic, member of the Freedom League.

Johnny Rocket

John Wade learned that his grandfather and namesake was the superhero Johnny Rocket during World War II on the day when an old foe sought revenge on the elder Wade and his family. A surge of adrenaline triggered Johnny’s own latent powers, giving him the superhuman speed he used to save his grandfather. Johnny’s speed has given him a reputation for leaping into action and he never hesitates when it comes to saving lives or doing what he thinks is right.

Keyword: Momentum

When you play Johnny Rocket’s hero deck in Sentinels of Earth-Prime, you’ll quickly notice some of his cards show the Momentum keyword either right under the illustration, or in the text that tells you how to use the card in play. A card showing that keyword under the illustration is known as a Momentum card, and when it’s in play it can be targeted by a card telling you to do something to a Momentum, and it will count toward the number of Momentum cards in play for effects based on that. As one of the fastest speedsters in the world, once Johnny gets going, he’s hard to stop!

Fast Footwork

Flurry of Blows

Example:

When Fast Footwork enters play, you draw 2 cards. Then, you may play 1 card. Since it has the Ongoing keyword, it stays in play, even though it has no further effects.

If you then play the One-Shot Flurry of Blows, you may destroy Fast Footwork (thanks to its Momentum keyword) to repeat the entire game text of Flurry of Blows. If you have other Momentum cards in play, you can destroy a new one each time you repeat the game text of Flurry of Blows, allowing you do to it all over again!

“How d’ya like that, slowpoke?!”

Lady Liberty

Pseudo

Pseudo is a rogue alien who defied the will of the Grue Unity to warn humanity of the impending invasion and aided the heroes of Earth-Prime in repelling it, using their innate shape-changing and telepathic abilities. Exiled without a world or a people, the Grue adopted the public name “Pseudo” and accepted the Freedom League’s offer to make Earth-Prime their new home and continue learning about and protecting its people.

Raven

Callie Summers grew up the daughter of wealthy Manhattan socialites Duncan and Jasmine Summers. It wasn’t until her sixteenth birthday that Callie learned her father was once the superhero known as the Raven, and that her mother was the daughter of his arch-foe Dr. Sin! She took up her father’s mantle and swore to honor her mother’s sacrifice. Now criminals feel a stab of fear once again when a winged shadow falls across them and they hear the voice in the darkness call “Nevermore!”

Siren

The Voodoo loa Siren, mistress of the seas, entered psychology student Cassandra Vale’s body and became as one with her to save her from a watery grave. She rose from the waters, riding on the back of a shark, and made short work of the pirates who tried to murder her. Since then, in times of need, Cassandra can transform into Siren to wield her mystic, elemental powers for the good of all.

Star Knight

Maria Montoya, the child of immigrants, became a police officer in California, hoping to help protect her community. She couldn’t have guessed that one day she’d become the Star Knight of Earth and join the Freedom League. Wearing a suit of alien power armor and wielding the energies of the Star Stone in the form of a powerful sword and shield, now she protects the Earth and all its people.

Eldritch (Expansion Deck)

Lantern Jack (Expansion Deck)

Meet the Villains!

Argo

Argo, the Ultimate Android

In their ongoing struggle with the Freedom League, the villainous high-tech Foundry constructed “Argo, the Ultimate Android,” an artificial being powered by a micro-singularity and able to reconfigure his protomatter form to mimic the powers of others. Argo is obsessed with eliminating the Freedom League and replacing biological life on Earth with machines like himself.

Hades

Meta-Mind

In the depths of space, on a shadowed world around an ancient star, was born the alien species known as the Grue. Metamorphic shape-shifters, the Grue share a telepathic group-mind, and the being known as the Meta-Mind is a living manifestation of it. In many ways, the Meta-Mind is the Grue, or at least their guiding intelligence, and all other Grue are just extensions of it, save for the few rogues who awaken to individuality, which the Grue hunt down to destroy and consume.

Omega

Malador the Mystic (Expansion Deck)

Malador, the Mystic

Malador was born millennia ago in the ancient realm of Atlantis. A master of the arcane arts, he earned the title of Master Mage, but betrayed his oath and his duty to humanity. Malador bargained with unspeakable evil entities from other dimensions beyond the ken of mortal minds. He sought power, knowledge, and eternal life above all else, and he will gladly betray the whole world to his monstrous masters.

Sentinels of Earth-Prime Quick Guide

Quick Reference

The players select a villain and an environment, placing the villain deck and villain character card in the villain play area, and the environment deck in the environment play area. The number in the top right corner of the villain character card represents that villain’s starting HP.
Follow the instructions in the Setup section of the villain character card.
Each player selects a hero, placing that hero’s deck and character card in their play area. The number in the upper left corner of the hero character card represents that hero’s starting HP.
Each player draws the top 4 cards of their hero deck. The object of the game is for the heroes to work together to reduce the villain to 0 HP.
Begin the game with the villain turn: Follow all “start of turn” instructions on the villain character card and other villain cards, play the top card of the villain deck, then follow all “end of turn” instructions on the villain character card and other villain cards.
Continue with hero turns clockwise from the villain.
Begin your hero turn by following all “start of turn” instructions for your character on cards in play.

Hero turns then have three phases: Play a card, use a power, draw a card.

All three hero turn phases are optional. If you neither play a card nor use a power, you may draw two cards instead of one.

End your hero turn by following all “end of turn” instructions for your character on cards in play.
End each round with the environment turn: Follow all “start of turn” instructions on the environment cards, play the top card of the environment deck, then follow all “end of turn” instructions on the environment cards.
Gameplay continues in the same order until either the heroes have all been incapacitated, or the villain is destroyed!

There is no limit to the number of cards a player may have in hand or in play. If a card needs to be drawn or discarded from an empty deck, shuffle that deck’s trash to recreate that deck and continue play as normal. Use the included tokens to track HP and damage modifiers during the game.
