If you are struggling to find the Tadpole Pens keycode, then we have the perfect guide for you. Here is how you can complete the Subnautica 2 Tadpole Pens quest.
Subnautica 2 Tadpole Pens Location and How to Investigate
In the ‘Investigate the Tadpole Pens’ quest in Subnautica 2, you will be asked to enter a keycode. This Tadpole pens quest can appear in one of the distress signals, or you can simply head to the location yourself, or head 600 metres East of the life pod to find it. Now, the Tadpole Pen keycode can be found by obtaining the Zip Blackbox.
The Tadpole Pens are located 675 metres East of the Life Pod. It is quite far, and I recommend you carry multiple food items and water to keep yourself safe. This is also a location where the Collector Leviathan, one of the famous Subnautica 2 Leviathans, is often found roaming, so be careful.
Once you have covered the distance, look for the Tadpole Pens below. It will have an open hatch, where you can enter and investigate the insides. In the right room, you will find a data entry that will tell you about the Tadpole Pens keycode location.
How to Get Subnautica 2 Tadpole Pens Keycode: Zip Blackbox Location
To find the Tadpole Pens keycode in Subnautica 2, you need to look for the Zip Blackbox. The simpler way to find it is to head back to your Life Pod or any place with an NOA Terminal and wait for a couple of minutes to get the Zip Blackbox signal. Using it will mark the exact location on your map, letting you easily explore.
However, if you don’t want to waste time by going back to your base or the Life Pod, then you can simply head Southwest for 200 meters from the Tadpole Pens until you find the hot caves. Go inside the hot caves until you reach a huge opening underground.
Now, look for the opening shown in the image and enter it to find the Zip Blackbox. You will have to go 250 meters deep to find it, so I suggest using a Tadpole vehicle to reach it. The accessible area of the Tadpole Pens has two Tadpole fragments, which would allow you to craft a Tadpole back at the base.
How to Open the Locked Door in Tadpole Pens
Once you have found the Zip Blackbox, head back to the Tadpole Pens and open the locked door on the left. Enter the new room and head upstairs. Turn on the NOA terminal to enable power and speak with Sophie Boucher to complete the quest. It will now mark the Alien Ruins on the map, where you can travel next to continue the story.
So, that’s how you can complete the Investigate Tadpole Pens quest in Subnautica 2. Have more questions about the questline? Ask us in the comments section below.
