FYI, it took a while for this to unlock for me after I'd reached the facility, probably 20 minutes or so.

I don't really have control over that, I simply wanted to inform people how to get to what's required for the achievement. I too have experienced delays in acquiring achievements from the game but so long as you fulfill all requirements you will get them... eventually laugh

It is *technically* possible to get there without any vehicles, though I wouldn't recommend it, particularly when the Cyclops at minimum is part of the required tech tree for the end game build.

If playing survival, make sure you take food and water when going to inactive and active lava zones for the first time. It's incredibly hard to navigate and you'll most likely be there a while. I wasted an hour because I forgot to bring water. Also, I wouldn't recommend using sonar for the cyclops down there as it absolutely shreds the battery. My cyclops died extremely quickly and it was stuck down there.

This one pops as soon as you swim down and discover whats at the bottom of the containment aquarium inside the base.
100% confirmed by me on multiple test accounts for my guide.

Can confirm the above. Saved last night at the top of the room. Got the achievement today when I reached the same point.

are but nothing. Will try again later.

You really need the drill arm modification when you do this and space in your storage to save a lot of messing about. I also highly recommend you don't take your Cyclops down there either was a pain in the backside to get it back out again in one piece :(

You are correct, that's my bad. Yes you do need the drill to do this to get the ion cubes necessary to power the gates. Also as for the cyclops, do NOT drop it into the hole that leads to the PCF; instead I highly recommend leaving it at the entrance that connects the inactive lava zone to the castle. Also, quick tip: remove ALL POWER CELLS FROM YOUR CYCLOPS BEFORR YOU LEAVE! Put 5 in the storage underneath and take one with you. This is to prevent creatures like the lava larvae and even the dragon from attacking it since it won't make any noise at all and won't actually be powered. Just remember that rushing back to your cyclops won't save you if you are in a pinch because there won't be any oxygen in it. As soon as you are ready to leave, plug the power cell in your inventory back into the cyclops (or all of them if you want) and then just turn it around and head back through the tunnel back to the inactive lava zone

In the “Active Lava Zone” location, somewhere further there will be a huge crater (like a volcano crater). Let's jump there. We look for a passage on the walls and move on, going lower and lower, deeper and deeper.
We end up on a lava platform where a dragon swims. Then it will be very difficult NOT to notice the insulating complex. But finding it and simply entering is not enough. We need to go further and deeper. Until you reach the end.

You can swim into that same crater on a glider with a pumped-up oxygen cylinder of 225 units; you don’t need to make upgrades to a diving depth of 1700, this will save you from one extra and long swim into a forgotten river on a cyclops, which is very tedious.
You just ride a crab to the edge of the crater and dive in by swimming. Near the complex, stay close to the bottom, but don’t touch it, and you can get back to the crab the same way or using teleports.
Ps just remember that you will need 2 blue tablets and a couple of ion cubes.
