This challenge is just four different files missing their extension. It's up to the player to figure out what type the file is and open it.

The four types are:

• Plain text file containing CTF{we-ar_______________}
• JPEG file containing CTF{_____e-all__________}
• PDF file containing CTF{__________-the-_____}
• ZIP file containing a text file with CTF{_______________files}

This isn't meant to be hard - in fact, Chrome can more or less recognize all 4.
