I'm in the regulator level. I've picked up the yellow, blue and green cards. I've turned off the steam just around the left corner and after cleaning up through the right door, proceeded down the metal walkway in front of the yellow steam valve. I've shot all the guards down there and entered the first room where I turned the wheel thing to maximum and got a message from Doyle... the problem is that outside steam is still spewing up from the grating in the corridor and I can't get past to the rest of the doors.

Have I missed something?

Cheers, John

It's OK, I found my way... just a senior moment back there.

Cheers, John
