## Solution
In the picture of this [tweet](https://twitter.com/OverTheWireCTF/status/1204370177237954565) there is a 2D barcode.
It's an Aztec barcode inside of a QR code. Here is a picture highlighting the Aztec code:

Scanning the inner Aztec code results in `414f54577b6234726330643373`, if you decode this hex into ASCII you get `AOTW{b4rc0d3s`-
Scanning the outer QR code results in `137:64:137:154:171:146:63:175` if you decode these octal numbers into ASCII you get `_4_lyf3}`

Putting the two together you get the flag `AOTW{b4rc0d3s_4_lyf3}`.
