</>What does Iron Lungs (Endless Stamina) do?
Stamina in Dumb Ways to Build runs out twice as fast as you'd like: sprinting drains it, and hauling a heavy beam across the site drains it faster still. Iron Lungs takes the bar out of the equation. Sprint from one end of the job to the other, carry the big stuff for as long as you like, and never get locked out of sprinting because you overdid it. The bar stays pinned at full the whole time the mod is on, and any exhausted lockout is cleared instantly. Switch it off and your stamina behaves exactly like it did before. A quiet quality-of-life boost that pairs nicely with Caffeinated for speed and Forklift Arms for strength.

</>Common questions about Iron Lungs (Endless Stamina)
What does Iron Lungs do in Dumb Ways to Build?
Iron Lungs keeps your stamina bar pinned at full in Dumb Ways to Build for as long as the mod is switched on. Normally sprinting drains the bar and hauling a heavy beam across the site drains it faster still, and when it empties the game locks you out of sprinting until you recover. With Iron Lungs you can sprint from one end of the job to the other, carry the big stuff for as long as you like, and never get locked out because you overdid it; any exhausted lockout is cleared the instant it appears. It is a single toggle with no sliders to tune, and switching it off returns your stamina to exactly the behavior the game shipped with.
Does Iron Lungs cover carrying heavy beams as well as sprinting?
Yes. Carrying is the bigger drain in Dumb Ways to Build, since hauling a heavy beam empties the stamina bar faster than sprinting does, and Iron Lungs covers both. The bar simply stays full whatever you are doing, so you can pick up the heaviest piece the delivery truck dropped, sprint it across the site, and still have the full bar when you arrive. What the mod does not change is how the beam behaves in your hands: a heavy piece still drags at you and still slips when it snags, because that is grip rather than stamina. If you want the beam to obey you as well, Forklift Arms from the same ProjectMods catalog handles hold strength, and the two mods are built to run together.
What happens to the exhausted lockout when I turn Iron Lungs on mid-sprint?
It clears instantly. If you switch Iron Lungs on while your Dumb Ways to Build bean is already wheezing through the exhausted lockout, the lockout is removed on the spot and the bar jumps to full, so you can sprint again immediately rather than waiting for the normal recovery. From that point the bar stays pinned at full for as long as the mod is on, so the lockout never comes back. That makes the toggle safe to flip at any moment during a job, including right in the middle of a sprint across the skyscraper. Turning it off mid-job is just as clean: the bar starts draining normally from full, and the lockout behaves exactly as it did before you installed the mod.
Does Iron Lungs make me faster, or just stop the bar draining?
Just the bar. Iron Lungs does not change how fast your bean moves in Dumb Ways to Build; it removes the stamina limit so you can keep sprinting and carrying at the game's normal pace for as long as you like. If what you actually want is more speed, that is a different mod: Caffeinated from the same ProjectMods catalog has a Speed slider up to five times normal and a Jump slider up to four times, and because sprinting still uses stamina under Caffeinated, the two are a natural pair. Run Iron Lungs alone for a subtle quality-of-life change that keeps the game feeling like itself, or run both when you want a bean that crosses the sewer in a few seconds without wheezing.
Does Iron Lungs affect my crewmates or only my own bean?
Only your own bean. Iron Lungs keeps the stamina bar full for the player running it in Dumb Ways to Build, and your crewmates keep the normal drain and lockout unless they switch the mod on in their own ProjectMods launcher. Because it is personal, there is no host to worry about and nothing to coordinate: a guest can run it in a lobby hosted by a friend who has never heard of it. It is also invisible to the rest of the crew in every way except that you never stop to catch your breath. In a mixed lobby that tends to make the Iron Lungs player the designated beam carrier, hauling the heavy pieces while everyone else saves their bar for the bits that need a sprint.
