You sit at the turret’s console, hands cold on the controls, and the mission title glows: Fire and Light. I watched the bearing sweep and felt the little knot in my gut tighten—this choice is a razor. I pulled the trigger anyway, like dropping a match into a powder keg.
I’m going to walk you through the fastest way to get the grim ending in IRON NEST: Heavy Turret Simulator. You can follow the official triangulation and play it clean, or you can shave minutes off your run by doing what I did. I race on Steam, post clips to Twitch, and keep an eye on speedrun.com; the route below is the monkey wrench people mention in the chat.
How to kill the king in IRON NEST: Heavy Turret Simulator
Speedrunners spot oddities and turn them into routines—this one started as a forum screenshot that looked wrong.
If you want the quickest ending, this is the method that gets you there. It skips the intended triangulation objective and targets a civilian position on the map—the game treats that hit as your king. The result: one shot, immediate self-destruct, and the fastest completion possible.
How do you kill the king in IRON NEST?
Step-by-step:
- Complete the opening mission that opens the Fire and Light objective.
- In the Fire and Light task, ignore the triangulation markers. You don’t need the map for this maneuver.
- Load a single HE shell, then add one powder charge.

What coordinates do I use to hit the king?
Precision matters here. Set your controls exactly as follows:
- Set bearing to 327.9° and wait for the turret to finish rotating.
- Raise the gun elevation to 57.12°. Don’t round these numbers—if you do, the shell lands somewhere else.
- Fire the shot and watch the impact on the map: it will land on a civilian position designated by the game as your king.

Why this route is the fastest — and why speedrunners grimace
On Twitch streams and forum threads I read, people bristle when a shortcut erases the intended challenge.
The gameplay consequence is immediate: when the shell hits that civilian marker, your Iron Nest detonates and you die in a ball of fire. The ending is blunt, emotionally hollow, and it’s the speedrun-friendly shortcut. I won’t pretend it’s noble; it’s an efficient end, like a guillotine’s whisper.

Is killing the king the fastest ending?
Yes—this is currently the quickest documented finish for a single-run completion. Speedrunners on speedrun.com and Twitch clip the moment and compare times. If you’re aiming for a record, expect pushback in the community for taking a route that avoids the intended objective.
If you want context, the game sells on Steam for about $14.99 (€15). Players post runs on speedrun.com, analyze frame-by-frame on Discord, and clip the awkward moral beat for Twitch highlights.
Final note: I advise against treating this as a moral choice—consider it a tool in your routing toolbox. Use it if your aim is a time attack, skip it if the narrative matters to you. Will you use the coordinates and shave minutes off your run, or will you let the king live to make a cleaner ending?
