Gloomhaven: The End of the World (Promo Scenario)
This is a digital, single-scenario promo item for Gloomhaven. After players fail a scenario, instead of retrying it, they can instead play this scenario to retroactively count the other as a victory, but the cost for losing is steep.
This scenario also adds a new mechanic of "taken" cards, where players lose cards to a separate stack, and these cards can only be recovered through a specific action.
The scenario can be purchased via the No Pun Included website.
