I'm at an impasse on level 11, PTMC Storage Facility, and need some assistance. This is the level where you have to rescue the prisoner. I'm at the cell block level but can't seem to activate the back up force field generators so I can destroy them. There are 6 switches on the inside of the hub which I can activate but don't get me anywhere. Do they need to be activated in a particular order? Did I miss a switch somewhere which also needed to be activated? Is it just a time thing (they switch back to active state in about 15 seconds)?
Any help would be appreciated. I did check the walkthrough on gamespot but it didn't help (only talked about activating the 6 switches).
TIA
