Keys

Keys in Coop Mode
When Heart Run is activated in the Coop Lobby, the players must defeat the Heart to win the run.

Just like in the base game, each player must gather a blue, red and green key. These keys can be found in treasure rooms, burning elites and rest sites.

Shared Keys
The total number of each colour keys required is equal to the number of players. A player can take multiple keys of the same colour, which will be distributed to their teammates as needed.

In the base game there is only one burning elite per floor. In Coop mode, multiple burning elites are generated on each floor to provide greater chances for teams to gather the red keys they need.

Tips

 * Stronger players can help weaker players by fighting multiple burning elites.
