01 / THE GUIDE
Technology Tree
Advancing through the technology tree unlocks new buildings and stronger units, reflecting the growth of your civilization over time. Each breakthrough opens fresh possibilities for development and combat.
The tree’s structure encourages strategic planning, as players must decide which technologies best support their current goals, whether expanding economy or enhancing military power.
- Compare the benefits of economic versus military technologies before committing resources.
- Prioritize technologies that unlock units needed for your preferred army composition.
02 / THE GUIDE
Army Composition
Front‑line units need resilience for direct combat, while second‑line units provide ranged attacks or specialized functions. Selecting the right mix is vital for success.
With more than 63 unique unit types, you can craft diverse formations that suit different strategies and opponent types.
- Balance front‑line durability with second‑line firepower for flexible tactics.
- Experiment with different unit combos to discover effective synergies.

03 / THE GUIDE
New Battle System
Each day, front‑line units of both armies clash if within attack range, while second‑line units also strike the enemy front line when possible. Casualties, retreats, and morale loss result from these engagements.
The system emphasizes positioning and timing, as the range of each unit determines its daily participation in combat.
- Position second‑line units to maximize their range against enemy front lines.
- Monitor morale changes after battles to anticipate retreats.
04 / THE GUIDE
Manpower Management
Manpower represents the pool of individuals eligible for military service. It is spent to recruit new troops and reinforce existing armies, reflecting a civilization’s capacity for war.
Manpower replenishes over time, mirroring natural population growth and recovery, so campaigns must consider both current and future availability.
- Plan offensives when manpower reserves are high to avoid shortages.
- Allow time for manpower to recover after large battles before launching new attacks.
05 / THE GUIDE
Buildings & Resources
Over 90 unique buildings can be constructed, each contributing to a more advanced economy. The game features 48 resources, each granting distinct bonuses to the civilization that produces the most.
Strategic placement of buildings and control of key resources can give significant advantages in both development and warfare.
- Focus on producing the resource where you can become the largest producer for its bonus.
- Use specialized buildings to boost the output of your most valuable resources.
