In the demo:

The Another Door multiplayer demo features the first biome of the full Another Door experience.

Travel through another door as friends or enemies for a party game where no two rounds are ever the same. Choose cards and risk your soul across tons of monster encounters, win prizes and fight for survival. You’ll need to be clever and bluff for your survival, as not every friend is truly on your side.

Think carefully before you walk through another door...

In the main game:

Hidden choices and well-guarded intentions: Play with up to 4 players online or on the same screen while keeping your choices secret

Risks and Rewards: Come face to face with desperate creatures, then collect your reward and end your adventure, safe in the knowledge that you'll get out alive, or continue, risking it all in the hope of obtaining more gems.

Control unique powers: From dragon’s skin to gifts from Mother, find boons and curses throughout to build your path out of the nightmare, or trip up your friends on the way out.

Battle the seasons: Random celestial events sow chaos with unpredictable effects

Multiple choices: Every encounter is a source of tragic decisions. You'll have to make the right choice at the right time. Will you be smarter than your companions in misfortune?

Forced friendships: Your relationship can save your skin or lead to your downfall. Honesty is one option, lying is another. How many betrayals can you accept before ending your friendship?

An endless adventure in a nightmarish environment:

Explore the world of Another Door, from deep dark forests to forgotten cities, and battle nightmares beyond comprehension to save your soul. Each journey through the doors is a new, panic-inducing battle of wits, bluffing and pushing your luck. In this world, there is only one question: What will you sacrifice to save your soul?
