Borderlands 3: How to Solve Tannis' Lab Puzzle

As a seasoned Vault Hunter with countless hours under my belt in the chaotic world of Pandora, I must say that solving Tannis’ lab puzzle in Borderlands 3 was a delightful challenge. The game usually guides you through its missions with clear markers and objectives, but this little brainteaser added an extra layer of excitement to the Angels and Speed Demons quest.


In Borderlands 3, the missions are usually clear-cut and straightforward, with their objectives clearly marked on the map and in-game directions helping you navigate from one room to another. However, some missions may contain small puzzles that can sometimes prove tricky to solve. An example of this is Tannis’ hidden lab where a specific objective necessitates solving a button puzzle within Borderlands 3.

Because her lab plays a significant role in both main missions ‘Angels’ and ‘Speed Demons’, it’s important to understand how to power up the reactor, which involves locating the correct buttons. This task isn’t particularly challenging compared to another puzzle, ‘The Desolation Cube’, that necessitates possessing every elemental weapon. Here’s a simplified guide on how to proceed.

In the depths beneath Konrad’s stronghold on Pandora, secretively lies Tannis’ laboratory. Upon reaching it via minecart and defeating all the Varkids within, you can initiate the Tannis puzzle by detaching the four connections in Borderlands 3. This task is straightforward, as it involves simply shooting the red couplings located centrally within the lab. Once you’ve done this, Tannis will instruct you to supply the reactor – but that’s where things get tricky.

In Borderlands 3, there are two control panels flanking the reactor. Generally, you’ll want to dash towards the larger one with four blinking lights. Unfortunately, you won’t be able to switch all four lights from red to green in this game. At best, you can get three of them to turn green before they all reset back to red. This console, however, is more of a diversion or a cunning trick designed to keep you occupied.

As a devoted fan, here’s how I’d put it:
