Cant stop Breen from using the teleporter.

[WinMar]

Helly everyone.

I've gotten to the top, and Alyx is behind some glass behind me and she is saying that i must stop Breen before he use the teleport to the other dimension. But how do i do that? I have already killed the two Gunships.

Shoot more balls into the core.

Yeah, there are shield type metal thingies that you must knock down in the core.

Thanks i found it. But damn, i thought you should follow Breen into the other dimension and fight him. Now im just sad :x
