After opening up misc60.zip inside **README.txt** we're greeted with huge strings of repetitive letters. Without spamming the page, here's just one 'block'.

Right off the bat, I notice the equals signs. Is this Base64 [again?](http://www.freeformatter.com/base64-encoder.html)

It sure is! And o-m-g it's a QR code made out of ASCII characters! Cute :3
Scrolling through the entire blocks of code. You'll notice that every block is a Base64 string, so if you paste all of the text in the **README.txt** into that decoder, you'll get A LOT of QR Codes in text.
Now, I'm sure there was a better way of doing this but this was me thinking on my feet, without a QR Code Reader/Scanner.
I took screenshots with [ShareX](https://getsharex.com/) of each of the QR Codes and uploaded them here: http://zxing.org/w/decode to get raw data out of them.
You'll notice that every QR code is actually a code of a letter. The one listed above was just **F**.
Decoding all the QRs you'll get the flag:
```
Flagis:IW{QR_C0DES_RUL3}
```
