Released in 2021, Hearthstone: Book of Mercenaries is a free, single-player content update featuring turn-based tactical card combat across 80 linear missions centered on unique mercenary stories. Players progress through class-specific adventures against AI opponents, with completion rewarding class-specific card packs. This mode offers a narrative-driven experience distinct from the main game's competitive focus.
This title is a free, single-player content expansion focusing on narrative adventure within a collectible card game framework. Released in 2021, it shifts the primary focus away from competitive multiplayer to deliver a structured, story-driven experience utilizing established turn-based tactical card combat mechanics.
The gameplay centers on a linear adventure format where players progress through a series of distinct missions. You engage in turn-based card battles against AI-controlled opponents. Success relies on strategic deck construction and in-the-moment tactical adaptation based on the specific challenges presented by each encounter.
The content is organized into distinct campaigns, each dedicated to a specific mercenary character and corresponding class. Players must complete a set number of missions—totaling 80 missions across ten different class storylines—to fully conclude that character's narrative arc.
What sets this mode apart from the base game's standard offerings is its emphasis on curated single-player challenges rather than open-ended ladder climbing or randomized dungeon runs. The experience is highly structured and narrative-focused.
For every class storyline successfully completed, players receive a corresponding class-specific card pack. This provides tangible progression rewards tied directly to the completion of the narrative content.
This content is accessible across multiple platforms, including PC, iOS, and Android devices, allowing for consistent access to the single-player adventure.
This mode is designed for players who prefer structured, narrative-driven challenges over open-ended competitive play. It offers a self-contained set of tactical puzzles that utilize the existing card game system but within a controlled, story-based environment.
