This is a shellshocker.io hack that actually works. Here is how to make it work.
1. Download Tampermonkey (an extension)
2. Copy the code from the "Code" section
3. Click the Tampermonkey Icon at the top right (the extension)
4. Press Create script
5. Delete the place holder code and paste the code you copied
6. After that press save
7. Go to shellshock.io and BOOM!
8. If it doesn't let you join, disable it by going to the top right, click the green bar, reload the page, click the bar again, and reload the page again.
BTW THIS IS NOT MINE! IT WAS MADE BY "TDStuart",I JUST WANT TO SHARE THIS WITH EVERYONE!!!
