Field Briefing
What Is Iron Nest?
IRON NEST: Heavy Turret Simulator is a first-person dieselpunk artillery game set inside a colossal war machine. You do not run across a conventional battlefield; you operate the turret, process intelligence, and prepare each shot through a chain of physical tasks.
The game combines tactical problem-solving with hands-on machine operation. Coordinates must become map marks, map marks must become firing data, and firing data must become a correctly loaded and aimed gun.
The current release is a single-player experience. Multiplayer is discussed by the developer only as a future plan — see the Wiki Hub for the sourced summary.
