Build and Conquer Alliances Guide
Choose an alliance purpose, discuss manageable country commitments, and reconsider the next shared objective after the first result.
An alliance in Build and Conquer should serve a shared country objective. Decide whether you want cooperation around city defense or a mainland strategic area before committing to it. The useful question is what both countries intend to accomplish together, not simply whether an alliance is available.
This combat example provides context for the conflicts a cooperative plan may need to address.
Agree on the purpose of cooperation
The game includes forming alliances, defending cities and fighting other nations for strategic areas. Those are different commitments. My recommendation is to make the alliance's purpose explicit before allowing it to determine your next military ambition.
A defensive purpose keeps the existing city central. An outward purpose concerns a deliberate strategic-area objective. Pick the one that fits your country rather than treating cooperation as a reason to join every possible conflict.
Give each country a manageable commitment
A country still has research, manufacturing, economic construction and city management to organize. Keep the shared plan narrow enough that those home-country tasks remain possible. A useful alliance goal should clarify your next session rather than replace it with several unrelated wars.
| Shared purpose | Country priority | What to discuss before committing |
|---|---|---|
| City defense | Protect what the countries already built | Which defensive goal is the immediate focus |
| A strategic area | Pursue a defined outward objective | Which area goal both countries intend to support |
| Military preparation | Prepare equipment for the same purpose | What each country is ready to commit |
These are editorial cooperation priorities, not claims about automatic alliance rewards, shared resources or a fixed limit on members. Keep the agreement focused on the task the game actually gives your country.
Reconsider the next objective after the first
An alliance can remain part of your strategy without making every later conflict part of the same plan. Once the shared objective has a clear result, decide whether the next commitment is still useful for your city and economy.
My preference is to preserve room for home-country management between outward ambitions. A strong economy supports warfare, while military preparation protects the country you developed. Cooperation should serve that relationship rather than consume all the attention behind it.
For an outward objective, read the strategic-area guide. For the wider country loop, use how to play. A useful alliance begins with a shared purpose, a manageable commitment and a clear reason for both countries to keep pursuing the same goal.
