Watch This: Portal 2 Gameplay

News about Portal 2 is flooding out of E3. Here’s the gist of what I’ve collected:

Portal 2 takes place after Portal; the Aperture Science facility is overgrown and exposed to the environment in several places.
GLaDOS is no longer playing around. She is now actively trying to kill you. The facility has become a lot more hostile, and it even reconfigures itself right before your eyes.
You have a small droid companion named Wheatley. His gameplay functionality is currently unknown. He speaks with a British accent and provides a lot of comic relief. His current vocal recordings are not final.
New puzzle elements:
- Orange paint that reduces friction and allows you accelerate faster. Blue paint that you can bounce off of. The paint is released by valves and can be sprayed through portals.
- Cubes with lenses on the faces that redirect heated laser beams.
- A kind of tractor beam tunnel that stops you from falling through it and can be redirected through portals.
- Vacuum devices with enough suction to pull objects through portals and tiles off walls.
An entirely separate two-player campaign where you play as two droids.
