There's like a new YouTube easter egg that I've been informed of so I might as well share it because I think it's actually pretty fun and a good time killer. It's a game by the way.
Instructions:
1. Go to any video of your choice
2. Press the following numbers in sequence - "1" "9" "8" "0"*
A game will appear.
*Indicates that you may need numlock.
How to Play:
Use your mouse to aim the cannons.
Left click your mouse to fire the cannons.
Objective:
Shoot the falling missiles before the brake and disable the video.
Notes:
Not sure if this is old or new.
I don't think you need to have numlock enabled.
I suggest to do this to a song.
