About IRON NEST: Heavy Turret Simulator
IRON NEST: Heavy Turret Simulator places you in the operator seat of a 5,000‑ton diesel‑punk artillery platform. Every lever, dial, and trigger is manually controlled, and a ballistic calculator translates your inputs into range, arc, and impact for each shell.
The campaign unfolds in an alternate‑history 1920s Spain on the brink of civil war. Handcrafted story elements, procedurally generated objectives, two challenge modes, leaderboards, and over 30 ammo types provide long‑term replay value.
01 / THE GUIDE
Heavy‑Artillery Simulation
Operating the turret requires turning the elevation wheel, selecting a propellant charge, and pulling the trigger. Each adjustment feeds the ballistic calculator, which instantly shows the projected trajectory, allowing you to fine‑tune distance and angle before firing.
The description warns that the machine can fail; jams and mechanical issues are possible. You must keep the turret functional while monitoring radio traffic and other tasks, as any failure is your responsibility, not the game's.
- Begin with low‑charge tests to verify range before committing to higher‑power shots.
- Watch the calculator’s read‑out for small changes that can prevent costly misses.

Interactive Tactical Map
The map serves both as a measurement tool and a live window onto the battlefield. You can move markers, view aerial photographs, and read intelligence reports that shape your firing plan before each engagement.
Two teleprinters feed information to the map: one delivers TOP‑PRIORITY directives from High Command, the other relays frontline calls. Both streams appear on the map, letting you adapt tactics as new data arrives.
- Cross‑reference aerial photos with intel reports to pinpoint enemy positions before firing.
- Use marker placement to plan smoke screens or other support actions in advance.

Procedurally Generated Objectives
Each playthrough creates a fresh set of mission goals, ensuring that no two sessions feel identical. Objectives range from breaching bunkers to providing cover for friendly withdrawals, demanding different tactical approaches each time.
These objectives are tied to newspaper reports that give context to the alternate‑history setting. The reports reinforce narrative themes while presenting new challenges for each run.
- Read the newspaper reports early; they often hint at hidden objectives.
- Match your current ammo loadout to the most relevant objective for efficiency.

Challenge Modes & Leaderboards
The game includes two distinct challenge modes that test speed, accuracy, and resource management. Scores from these modes are posted to global leaderboards, allowing you to compare performance with other operators worldwide.
Leaderboards provide a clear metric for improvement across multiple runs. By refining firing solutions and reducing wasted charges, you can climb the rankings and demonstrate mastery of the turret.
- Aim for consistent accuracy to improve your leaderboard ranking.
- Practice faster charge selection without sacrificing precision to boost scores.

Customizable Cat Companion
A feline sidekick accompanies you on the turret platform. The cat is fully customizable, offering visual variety such as different fur patterns and accessories, though these changes do not affect turret performance.
Customization options become available as you progress through the game. The menu lets you select new appearances, providing a lighthearted visual element while you manage the heavy artillery.
- Check the customization menu after each session to see newly unlocked options.
- Use the cat’s presence as a visual break during long firing sequences.
