Stuck in Overature, Ch 3

[Dogmauler]

If not, I'll, as a last resort, do an intentional spoiler. I'm replaying it anyway.

By the way, I've played all Black plague (All difficulties), all of overture, and a lot of Requiem. I'm having more than a little trouble on this one part. You know when the portal takes you to a place with a lot of chain-link and concrete, and red talks to ya over the radio? I need some help getting started....I've already put a crate on one switch.

Hope I can help, and hope I get some help.
