IRON NEST: Heavy Turret Simulator From Demo Cab to Full Campaign
How to leave Next Fest training behind and fight across alternate-history Spain.
The free Steam demo teaches the language of IRON NEST. The full campaign, available since August 6, 2026, is where that language becomes a war story. You still read teleprinters, plot on the tactical grid, solve ballistics, and haul elevation wheels by hand —but now the map widens across 15 regions, shells and abilities unlock over time, newspapers remember your choices, and medals track how cleanly you operated.
This guide is the bridge between demo operations and sustained campaign play. If you have not yet landed a single deliberate hit, stop and complete the first firing solution first.
Buy full game or keep drilling the demo?
Keep the demo (app 4300500) if triangulation still feels opaque or you bounce on calculator workflow. Buy the full game if the loop already feels addictive and you want story missions, progression, and leaderboards. Launch week often includes an introductory Steam discount —see launch reception for the offer window and review climate.
Demo progress should be treated as training, not a promised save migration, unless developers explicitly announce otherwise.
Day-one checklist
| Step | Why |
|---|---|
| Verify PC against system requirements | Avoid first-mission stutter during bombardments |
| Skim Version 1.0 notes | Learn wear, FOV, and Emergency/Tactical Move |
| Rehearse one demo mission | Confirm your personal pre-fire checklist |
| Open ammunition hub | Know HE vs AP vs smoke/star before story pressure |
| Bookmark newspaper consequences | Campaign choices echo on front pages |
| Note medals and achievements | 100+ medals and 33 Steam achievements track mastery |
How the campaign differs from the demo slice
Length and geography. Demo operations sit on a compact training coast. The campaign spreads across 15 regions of alternate-history late-1920s Spain —monarchy versus republican uprising —described in more detail on campaign regions. Expect longer travel between narrative beats and more varied terrain that changes how range and charge choices feel.
Progression. Full release unlocks a deep ammunition list (~30 types) and crew/machine abilities. Early missions still teach; later ones assume you can triangulate under time pressure while managing requisition and upgrades from progression and abilities.
Consequences. Story missions feed the newspaper system. Shell choice, collateral risk, and obedience to High Command are not flavor text —they become headlines. Read newspaper consequences before you treat every order as morally free.
Replay modes. Steam lists two challenge modes with leaderboards and procedural objective layers on handcrafted missions. The demo’s Challenge: FDC is your preview; the full set is covered in challenge modes.
Suggested first week in the Nest
Session 1 — Confirm the loop. Buy or install the full game, finish the opening calibration-style missions without rushing. Use teleprinter intel and map measurement guides only when stuck.
Session 2 — Corrections under pressure. Deliberately miss once, then walk rounds with star shells using artillery corrections. Version 1.0 wear means a “mystery miss” after a long barrage may be the gun talking —re-check elevation before blaming the map.
Session 3 — Counter-battery literacy. When spotters disagree or enemy guns range you, apply triangulation and spotting. Decide whether Emergency Move or Tactical Move is worth the signature cost (Version 1.0).
Session 4 — Shell doctrine. Stop defaulting to HE. Open the shell tier list, then specialized pages for AP, smoke/star, and restricted chemical/incendiary loads.
Session 5 — Challenge score attack. After story comfort, run a challenge mode for leaderboard practice. Keep a separate mental model from narrative missions —score attacks reward speed; newspapers punish spectacle.
Cab habits that survive the whole campaign
- Copy Nest-to-target bearing and range last; delete scaffolding notes from interim spotter legs (clipboard guide).
- Match shell, charge, and elevation as one ticket —changing one value means recomputing, not patching by feel.
- Use recon photos as truth, not vibes.
- Treat High Command urgency as a timer, not permission to skip measurement.
- When relocating, finish critical loads or secure the breech mindset before you move the whole 5,000-ton machine.
Platforms and input
Campaign play is single-player on PC stores. Full controller support exists for couch or Deck-style sessions —see default keybinds and physical gun controls. Single-player only: every miss is yours alone.
Where this wiki fits after launch
Use the guides hub for procedures, systems hub for progression and newspapers, updates hub for store and patch context, and review hub for expectations. The Nest does not get easier because reviews are Overwhelmingly Positive —it gets busier. Arrive with a checklist, leave with a headline you can live with.
Frequently Asked Questions
Quick answers to the most common questions.
Should I finish the IRON NEST demo before the campaign?
Strongly recommended. The six demo operations teach the same instruments the campaign assumes you already understand.
How many regions are in the full campaign?
Steam lists 15 campaign regions set in alternate-history Spain.
Do newspapers change how I should play?
Yes. Mission outcomes and controversial shell choices can appear as headlines —read the newspaper consequences guide before treating every order as consequence-free.
Are challenge modes part of the story campaign?
No. They are separate score-focused modes with leaderboards. Learn the story loop first, then chase times.
Does demo progress carry into the full game?
Treat the demo as training. Unless developers announce save transfer, do not expect demo clears to unlock campaign progress.
