The "Necropolis" event in Darkhaven introduces a wave of undead that obstructs player waypoints and populates the environment with skeletal minions. Players can transfer characters to new worlds, facing challenges like volcanic eruptions, rising floodwaters, or ice ages. The game features modular gameplay events that can be procedurally integrated into the world. Players can interact with each other's worlds and utilize terrain deformation and building systems for strategic gameplay. Darkhaven aims to rejuvenate the action-RPG genre by focusing on organic experiences and player agency, moving away from rigid progression systems. The game emphasizes diverse loot systems and player impact on the environment, creating a living world that reflects players' actions. The development team includes veterans from the original Diablo, and they are preparing for a Kickstarter campaign.
