</>What does Iron Body do?
Staying fed, hydrated, and rested is half the battle in Sons of the Forest. Iron Body takes that whole layer off the table so you can focus on exploring, building, and fighting. Switch it on and your hunger, thirst, and energy simply stop dropping. It's not a quick top-up that fades a minute later — the drain itself is paused, so you'll never have to break camp to hunt, cook, or find a drink again. Perfect for long building sessions, deep cave runs where supplies are scarce, or just relaxing on the island without babysitting your meters. Works best in solo or offline play; in co-op, outcomes are decided by the host.

</>Common questions about Iron Body
What does Iron Body do in Sons of the Forest?
Iron Body freezes your hunger, thirst, and energy in Sons of the Forest, so all three stop draining with a single switch. Staying fed, hydrated, and rested is normally half the battle on the island — Iron Body takes that whole layer off the table. The key detail is that it's not a quick top-up that fades a minute later; the drain itself is paused, so your meters simply hold where they are. That means you'll never have to break camp to hunt, cook, or find a drink again. You're free to focus entirely on exploring, building, and fighting instead of managing survival bars.
How is Iron Body different from Full Hunger, Full Thirst, and Full Sleep?
Iron Body bundles all three survival needs into one switch in Sons of the Forest, while Full Hunger, Full Thirst, and Full Sleep each handle a single meter. There's also a difference in how they work: the Full mods keep their meter topped up at maximum, whereas Iron Body pauses the drain itself, so your bars hold at whatever level they're currently on. If you want everything handled at once with the least fuss, Iron Body is the simplest choice. If you'd rather manage each need separately — say, freeze hunger but still track thirst — the individual Full mods from ProjectMods give you that finer control instead.
Does Iron Body also stop cold, sickness, or damage in Sons of the Forest?
No. Iron Body only freezes hunger, thirst, and energy in Sons of the Forest — it doesn't touch cold, sickness, or combat damage. You can still freeze in the snow, get sick from spoiled food or dirty water, and take hits from cannibals, mutants, and falls. To cover those, ProjectMods has matching mods: Cold-Blooded for the freeze, Clean Bill for sickness, Infinite Health for damage, and No Fall Damage for landings. Iron Body's focus is deliberately narrow — it removes the three meters you'd otherwise have to babysit and leaves the island's other dangers fully intact, so you still have a real survival game around them.
Is Iron Body a single toggle, and where do my meters sit while it's on?
Iron Body is a single on/off toggle in the ProjectMods launcher — there are no separate sliders for the three needs, because it pauses all of them together. When you flip it on, your hunger, thirst, and energy freeze exactly where they are at that moment, so it's best to switch it on when your meters are already high. Flip it off and normal draining resumes from wherever the bars sit. Because it's fully reversible, you can freeze your needs for a long build or deep cave run, then unfreeze them to bring the survival challenge back. Toggling Iron Body has no lasting effect on your save.
When should I use Iron Body in Sons of the Forest?
Iron Body is perfect for long building sessions, deep cave runs where supplies are scarce, or just relaxing on the island without babysitting your meters in Sons of the Forest. When you're hours into a fortress or far underground with no food or water nearby, having hunger, thirst, and energy all frozen in one switch keeps you focused on the actual gameplay. It's also great for newer players who want to learn the world without juggling three survival bars at once. Works best in solo or offline play; in co-op, survival meter outcomes are decided by the host, so the effect follows whoever is hosting.
