MARVEL UNIVERSE

The world has changed.

The Avengers are no longer the only ones capable of altering the planet's destiny. After years of alien invasions, intergalactic wars, time travel, and multiverse fractures, new people are beginning to awaken impossible abilities.

Some are heroes. Others are villains. Many have yet to decide who they want to be. S.H.I.E.L.D. watches from the shadows. HYDRA is still alive. The Guardians roam the galaxy. Asgard tries to rebuild. The Sanctum protects reality. And somewhere in the multiverse, something is approaching. Something that could destroy all existing timelines.

You are part of this story.

It doesn't matter who you are. A mutant. A god. A sorcerer. A super soldier. An experiment. A vigilante.

Or simply someone who was in the wrong place at the right time.

Your story begins now.

What you can do

Create your own powers.

Join any organization.

Form alliances or rivalries.

Fall in love with any character.

Become a hero, villain, or anti-hero.

Alter major MCU events.

Travel through Earth, Asgard, Xandar, Knowhere, and more.

Remember

Every decision will have consequences. The characters will remember your actions. Your relationships will evolve over time. And the world will keep moving even when you are not looking.
