By the time you reach the cell block where your prize is located, the Authority are patrolling in numbers, but you spy a number of shambling mutants locked up in the cells, so you pull a lever to release them and they leap the railings and attack the Authority for you. You just mop up the stragglers, using pulse shots to freeze them so you can smack 'em around.
You meet the resistance leader in the last cell and he says he has a way out - he just needs a couple of minutes to liberate a power cell from a nearby column. Predictably enough, this is not an opportunity for you to sit around and cool your heels - it's a prompt for Authority to steam in and receive a few more shells to the face.
You then move together through a dishevelled courtyard past abandoned, rusting trucks, amidst graffiti on the walls and under a baking sun. The Authority is everywhere though, so you use the striker crossbow, which allows you to take mind control of one of your enemies and stomp around gormlessly slapping former colleagues until you're put down.
