How to unlock the Iron Lung achievement in Call of Duty: Black Ops III - Definitive Guide
Note: The gas mask helps to survive longer underwater.
In Zetsubou No Shima, stay underwater for one minute.
To obtain this achievement you must stay underwater by using the spores to regain air when you start to take damage. If you use the gas mask as you can breath underwater for ~30 seconds with it equipped.
This video will show you were you need to go and how to do it. The video is in 1080p 60fps. I hope this guide helps!
As far as I know, the only place to do this is in the same water tunnel you get the wheel for the Pack-a-Punch as well as the plant for the KT-4.
Simply go under water and swim around. Within the tunnels will be 3 orange spores, if you shoot or bump up against them they will explode and give you oxygen. Make sure your character begins to gag for air and then pop one, do the same for the next 2 and your trophy will pop after a minute has passed without surfacing for air.
Note: One of the orange spores is at the very very far end of the tunnel immediately beside where you grab the plant piece.
1) Build and Equip gas mask ( lets you hold your breath for longer)
2) Go to where you turn on power in the bunker (Back of map)
3) As you start to choke shoot the yellow spore in the corner so air bubbles pop out ( this will keep you alive)
4) Time on your phone so you don't stay longer than you need to as the trophies can have a few seconds delay
This easy trophy can be done as soon as you have access to the Underwater Tunnels, but can be made even easier with a Gas Mask and Juggernog. Simply stay underwater for 1 minute straight without going up for air and the trophy will pop. Normally you can’t survive more than 20 seconds, but in the Underwater Tunnels there are orange spores that you can shoot which will release air bubbles. Simply go underwater, wait until your health flashes 3 times, then hit a spore, wait another 20 seconds until you lose health again, then use 1 more spore to have more than enough time for the trophy! With Juggernog you can take 6-7 hits before drowning and with the Gas Mask it takes longer to damage you, so if you’re having trouble wait until you have those!
