Well, the three/four guys that were already in the tunnel keep using air attacks, which trigger the strong attacks from the robotic creature. Should I wait for them to be defeated before I start attacking? Am I to understand the lever will disable the creature for a round?
Those guys take quite a chunk out of it - I tend to support them to keep them alive but, with the weapons turned off, the machine doesn't do a lot of damage and their air attacks don't trigger anything. Without the control box, I don't know. I defeated it once that way (after a lot of help from Raze) but opted to use the control box every other try. It was my very first play through so I don't remember how I did it - luck probably.
Vometia: are you sure it wasn't working? I don't think there's a message or anything - it keeps fighting with the weapons disabled option - just doesn't do much damage.
