How to Find the Biodecryption Key

Learn how to find the Biodecryption Key in Gotham Knights. Discover which devices and samples are required to unlock this crucial item in The Langstrom Drive.

Alright, let's figure out how to get this Biodecryption Key. It sounds more complicated than it is, so don't sweat it. We're looking for a specific item, and the game gives us a few options to choose from, but only one combination actually works.

First off, you'll need to know what kind of devices might have this key and what samples are needed. The game lists these out:

• Potential Devices: Blood Glucometer, Langstrom’s Phone, MMO Key Fob, Pulse Oximeter
• Required Samples: Blood Vial, Soft Tissue Samples, Urine Samples

The key here is to realize that most of these just won't work together. For example, you can't really use urine samples with a pulse oximeter, right? The game hints that Langstrom wasn't in perfect health, but also that he wasn't a diabetic, which is a bit of a red herring for the pulse oximeter.

The real trick is to go for the Blood Glucometer and the Blood Vial. These two are the only ones that make sense medically and interface correctly.

So, here’s what you do:

1. Navigate to the Blood Glucometer in the game interface.
2. Highlight it and press the / button to select it.
3. Next, navigate to the Blood Vial.
4. Highlight it and press the / button to select it.

Doing this will successfully reveal the Biodecryption Key. Easy peasy!
