01 / THE GUIDE
Civilizations and Home City Cards
The game includes 18 distinct civilizations, comprising the original roster plus the Swedes, Inca, Mexico, and USA. Each civilization provides unique bonuses that affect resource gathering, unit production, or combat performance.
All Home City cards are unlocked by default, allowing players to select pre‑built decks or craft custom decks without additional progression. This removes the need to grind for card acquisition before competitive play.
- Review each civilization’s bonus list to match your preferred playstyle before selecting a deck.
- Try a pre‑built deck first to learn card interactions, then experiment with custom selections.
02 / THE GUIDE
Co‑op Historical Battles
Two players can team up to tackle nine scenario‑driven missions inspired by real historical events. The mode presents objective‑based battles where both participants share responsibility against enhanced AI opponents.
Design of these missions encourages coordination, letting each player focus on different aspects such as economy or combat while pursuing common goals.
- Assign one player to manage resource production and the other to lead combat units for balanced teamwork.
- Discuss target priorities early to avoid duplicated attacks on the same enemy.

03 / THE GUIDE
Art of War Challenge Missions
Challenge missions offer focused scenarios that test economy, tactics, and combat execution. Players aim for Gold Medals, providing a clear benchmark of mastery for each scenario.
These missions serve both newcomers learning fundamentals and veterans refining advanced strategies, as each challenge isolates a specific gameplay element.
- Prioritize early resource gathering to establish a strong economic base before expanding your army.
- Replay a mission after adjusting one variable—such as villager allocation—to see its impact on the medal rating.

Maps and Revolutions
The edition adds 30 new maps, expanding the variety of battlefields available for skirmishes and other multiplayer matches. Each map introduces distinct terrain features that influence unit placement and movement.
Revolutions have been overhauled, with examples like Brazil, Indonesia, and Egypt providing nation‑specific cards and units. Political choices during a Revolution grant additional strategic options.
- When selecting a map, note terrain types that favor your civilization’s unit strengths.
- Choose a Revolution whose exclusive units complement the map’s layout for a tactical edge.
