How to use this achievements guide
For IRON NEST achievements, start with the visible Steam requirement, then record the mission, build date, and action immediately before an unlock. This gives each route a checkable context instead of treating an achievement title as proof of a hidden trigger.
Build a route without spoiling unsupported details
For each achievement, record the requirement text, the operation where it was tested, the build date, and whether the unlock occurred. A route should distinguish confirmed steps from player reports and untested theories.
Use a verification record
When an achievement unlocks, record the visible requirement, mission or mode, build date, and the action immediately before the unlock. If it does not unlock, keep the attempt as a failed test instead of turning a player report into a guaranteed condition.
What remains unverified
A useful route needs real mission order, missable warnings, and reproducible conditions. Hidden triggers and exact achievement routes remain unverified until they are observed in the current build rather than copied from another guide.
