Portal 2 'Turrets' trailer answers age-old question

By Richard Mitchell

Valve has released the third Portal 2 trailer featuring Aperture Science president Cave Johnson, this time featuring the company's iconic automated turret. The video answers a lot of questions about everyone's favorite talking gun.

For example, in how many designer colors is each turret available? Answer: Hundreds. Also, did you know Aperture turrets fire the entire bullet, and not just the slug? It's true! The most important question, however, is just how does Aperture cram so many bullets into its turrets. The answer is a lot simpler than you might think.


Protip: Watch in full screen and HD to read the diagrams. It's worth it.
