By focusing on each core pillar, you can streamline decision‑making and improve overall performance without relying on external tutorials.

Base Expansion Planning

Map out facility upgrades before launching missions. Compare the cost of new research labs versus additional barracks, noting how each choice impacts soldier readiness and tech unlock speed.

  • Balance soldier recruitment with facility construction to avoid resource bottlenecks.
