Vault Zero is a combination deck-builder, engine-builder, and action programming game set in a techno-dystopian future. Players take the role of rebel hackers who are all working to build machines that can hack into Vault Zero, the digital fortress that contains the government's darkest secrets, and expose those secrets to the public and cause a mass uprising.
Players begin each turn with only one actin available to them, but cards they collect can add action economy in three different ways depending on their color. With a full board players will be triggering effects that trigger effects that trigger effects. Find effects that generate Key cards and get 5 of them in your hand at once to steal a secret from the Vault! Steal your 5th secret, and you've won the game!
