Quick answer

Mission 1 of IRON NEST teaches the complete firing loop: read your first order, measure the target on the map, calculate the solution, load exactly what the card says, fire, and correct once. Specific Mission 1 objectives have not been verified from official sources — this page documents the community-tested routine that gets through it and clearly marks what is 待确认 (unconfirmed). Verified August 12, 2026.

What the first mission is for

Community reports describe the first mission as the game's practical tutorial: the campaign teaches the operator routine mission by mission, starting with a single fire mission. The Steam page confirms the campaign is a handcrafted story in alternate-history 1920s Spain — but the specific script of Mission 1 is 待确认 (unconfirmed).

The routine that works for the first mission

The community-documented 11-step loop applies directly:

  1. Check the mission — read the teletype order; copy the target and bearing exactly.
  2. Measure the target — mark the reported position on the tactical map.
  3. Calculate the solution — enter distance, choose shell and powder charges, confirm elevation.
  4. Write the firing card — all five numbers: bearing, distance, charges, elevation, shell.
  5. Dispense the ammunition on the card.
  6. Load the gun — ram the shell, insert charges. Remember the one-way rule: nothing can be undone.
  7. Set bearing on the armed gun.
  8. Set elevation.
  9. Arm and fire.
  10. Read the impact.
  11. Correct once — one variable, then re-fire.

Players who wrote the card before loading reported far fewer failed first shots; a wrong digit on the gun becomes a wrong shell on the target.

The counter-battery timing

Community tests agree that enemy counter-battery fire starts after your first round impacts. In Mission 1, that means your first shot starts the clock:

  • Have the second solution planned before the first round lands.
  • Correct one variable at a time after reading the impact.
  • Do not hesitate on reload — the magazine is limited (community reports say six rounds per magazine).

What is still unconfirmed about Mission 1

  • The exact objective text and any optional objectives — 待确认 (unconfirmed).
  • Whether Mission 1 includes the collectible newspapers/records seen in later missions — 待确认 (unconfirmed). (Patch records confirm collectibles exist in a mission called High Tide, fixed in Build 1558.)
  • Any gold/medal conditions for Mission 1 — 待确认 (unconfirmed).

This page will be updated when Mission 1 is verified against the current build. No walkthrough numbers are invented here.
