The turrets facing each other4 hints left
They're surrounded by anti-portal materials! Time to get creative.

What do I do?

The glass in this chamber is bulletproof, so be sure to use that to your advantage.

Examine the area around the turrets closely. Do they have a blind spot?

Hmm...

For the nearest turret, you've got two options:
  1. Find something bulletproof and CHARGE!
  2. Look for a blindspot and exploit it

Help me out.

  • For option 1, just grab a cube and throw it at the turret by left-clicking.
  • For option 2, put a portal on the 'X-marked 'ceiling above the turret and drop a cube through it.

What about the other turret?

The berserker option doesn't work quite so well when your back is exposed, so repeat the trick used for option 2 (and remember, you've got a few seconds to create a portal on the ceiling before it starts shooting.)
