The Orange Box: Portal Hints
How can I get rid of these pesky turrets?
1 of 7: With energy orbs.
2 of 7: Notice that there's a rotating energy orb firer in the room.
3 of 7: Also notice all the black marks on the walls where energy orbs bounce off of them.
4 of 7: Give you any ideas, portal-meister?
5 of 7: What if you fired a blue portal at one of the black mark spots, and then fired an orange portal at one of the spots where the turrets' red lasers hit the wall?
6 of 7: If you do that, you can just wait for that turret to get knocked off by an orb.
7 of 7: Repeat until all four turrets are deactivated.
