Age of Wonders 4: The Silver Seas is a strategy RPG expansion that brings naval exploration and empire building to the turn-based 4X framework of the base game. Players expand across land and sea, customize factions with new maritime options, and engage in tactical battles while managing resources and diplomacy in a fantasy setting.
Gameplay
The core loop centers on realm creation, faction customization, and turn-based progression across a world map. Players select or build rulers, choose forms and cultures, research tomes for spells and units, and annex provinces to grow cities. The Silver Seas expansion adds the Mercantile culture, which emphasizes profit through deals and alliances while allowing city placement on both land and sea. Subcultures include the Cartel, focused on information and manipulation, and the Barony, centered on trade princes who issue bounties.
New forms such as the elegant Aqualon and the fierce Sharkkin enable specialized sea-based playstyles, with an additional society trait for transforming populations into Merfolk. Four new tomes expand magical options: Tome of Hydromancy for ally support and enemy vulnerability to lightning and frost, Tome of the Damned for ghostfire effects and summoning, Tome of Piracy for mobile skirmishers and plunder tactics, and Tome of Eternal Ice for freezing oceans after earning its power. A new dwelling called the Bond of the Free Captains introduces pirate captains with distinct personalities, allowing alliances or conflicts that unlock units and technologies.
World map additions include ocean events, landmarks like the Tempestuous Vortex and Armada's Fall, ancient wonders such as the Uncharted Harbor and Pearltide Dome, the Spawning Shoal infestation, and the Pale Tidebloom magic material. New sea creatures like Frenzied Fish Swarms, Accursed Wisps, Hoarfrost Mantas, Seamare, and Lightning and Storm Rune Crabs add combat encounters. Interface skins, music tracks, a Seamare mount, and realm templates further support immersive sessions.
Game Modes
Age of Wonders 4 supports singleplayer experiences through customizable realms and story-driven scenarios where players build empires against AI opponents. Multiplayer options allow competitive or cooperative matches with up to nine participants, using either classic sequential turns or simultaneous turns for pacing variety. The expansion integrates directly into these modes by adding sea colonization and maritime events to existing maps and new realm templates.
Tactical combat occurs on hex-based battlefields during clashes, emphasizing unit positioning, spells from tomes, and morale. Victory paths include military domination through conquest, expansion by controlling provinces and structures, magic achievements via research and wonders, and score-based tallies of overall performance.
Key Features and Updates
The Silver Seas expansion releases on November 3, 2026, as the first major addition in Expansion Pass 4. It builds on ongoing support for the base game with new content focused on aquatic themes. Players encounter six pirate captains in the new dwelling, each with unique ambitions that influence diplomacy and rewards. Additional wildlife units and map surprises enhance exploration without altering established mechanics.
Is It Worth Playing?
The base game delivers deep customization and replayability through its 4X systems and tactical combat, appealing to fans of strategy RPGs who enjoy faction building and long campaigns. The Silver Seas expansion extends these strengths with sea-focused mechanics, new cultures, and map variety that encourage fresh strategies around naval dominance and trade. Those who value detailed empire management and modular magic systems will find the added content a natural extension. Availability on PC aligns with the platform focus, and the expansion requires the base game for full access.
