Darfall frames its fantasy campaign around protecting a settlement from the undead. Players explore Aganor through challenging missions, with each day offering time to gather resources, strengthen the town, and investigate nearby lands. Night shifts the emphasis to defending homes and people from enemy waves until dawn, giving the game a clear rhythm of preparation followed by survival.
Heroes add a character-driven layer to that cycle. Wizards, warriors, and others bring varied skills that can be developed, while powerful artifacts earned during the adventure offer another way to equip them. The game also includes a survival mode built around escalating nightly threats, followed by a morning rebuilding phase. Alongside its authored challenges, an in-game editor lets players create scenarios, maps, quests, and scripted campaigns to share.
Its appeal lies in balancing settlement preparation with defense, then carrying that strategy through hero development or custom-made adventures.
