The Crucible is a Downloadable Content (DLC) that introduces a challenging new arena gameplay mode to Grim Dawn.
The Crucible was conceived as a stretch goal during Crate's successful Kickstarter campaign. Originally called Survival Mode, it was described as follows: “In survival mode players will fight to stay alive against increasingly difficult waves of monsters.” The DLC was made available for free to those who purchased the game prior to or during the Kickstarter campaign.
