IRON NEST combines a handcrafted story with procedurally generated objectives across 15 regions and two Challenge modes. The developer estimates roughly 8–12 hours to complete every campaign mission once without replaying, but does not publish a stable total mission count in the reviewed official sources.
What the reviewed sources establish
- The store lists 15 regions, two Challenge modes and procedural objectives.
- The FAQ gives an 8–12 hour estimate for one pass through every mission.
- Challenge Missions provide varied targets, progression and leaderboards beyond the campaign.
Use this current-build checklist
- Copy the current directive and separate story context from actionable data.
- Record target, requested effect, source and time pressure.
- Measure and calculate for the current run rather than a numbered walkthrough.
- Read the newspaper and communications before preparing the next mission.
Keep the answer current
- Do not turn the playtime estimate into a fabricated mission count.
- Mission 2 or 3 details can vary by build and run.
- Exact coordinates from another player may be stale.
Verification boundary
What still needs live verification
The reviewed official pages do not provide a permanent numbered mission list or answer key, so this guide does not invent one.
Official descriptions establish stable scope. Interface paths, balance, values, rewards, schedules, and version-specific behavior must still be checked in the current game build.
