Build and Conquer Tunnels Guide

Last updated 2026-10-10Unofficial player article

Understand tunnels as the mainland deployment route, prepare the country behind the force, and choose a useful task after arrival.


Tunnels in Build and Conquer connect troop deployment to the mainland. Treat them as the route between home-country preparation and your military objective, then decide what the force should accomplish after it arrives. A route is useful when it serves a campaign you have actually planned.

This combat example gives a view of the outward fighting context before you prepare your own mainland operation.

Tunnels have a deployment purpose

The confirmed country loop includes researching technology, manufacturing vehicles and missiles, and deploying troops through tunnels to the mainland. Keep the tunnel route connected to the force's task rather than treating it as an isolated construction ambition.

My recommendation is to choose the mainland goal first. A limited objective gives the route a reason and keeps the session from becoming an open-ended search for any available fight.

Prepare the country before the outward commitment

Equipment preparation and mainland deployment are different tasks. Finish a purposeful preparation plan before turning the session toward outward operations. At the same time, retain attention for the city and economy behind the force.

This explains the route's role without inventing tunnel coordinates, interface buttons or a fixed unlock cost. The useful distinction is where preparation ends and mainland operations begin.

Arrival should lead to a chosen task

The game includes alliances, city defense and fights for strategic areas. Decide which of those broader ambitions your deployment belongs to before letting the force's presence on the mainland become the only reason to attack.

A deliberate first objective gives you a stopping point. Once you have pursued it, you can decide whether another operation belongs in the same session or whether the country needs your attention at home.

Continue to troop deployment for the force-preparation checklist. Use the troops guide when ground-force planning is the immediate question. Tunnels serve the connection between country and mainland; the campaign plan gives that connection its practical value.
