Aperture Science does what it must because it can in new Portal 2 vid

Considering picking up a sentry turret? You may want to look into the Aperture Science range shown here. They’re pretty darn effective when it comes to pumping bullets into something. We’re sure that you’ll learn that pretty quickly in Portal 2 though, where these things are going to get in your way quite a bit.

At least they’ll be polite about killing you.

Portal 2 launches later this month.
