InFAMOUS/Alden in Chains

Start by running to the left of the main prison entrance and climbing through the hole in the prison wall. Find Zeke in the rear of the prison yard and then climb up to the electrified walkway.

Get to the roof
First up are a bunch of meteors from Conduit trashbots. Use Shockwave to deflect the missiles. After the wave of meteors, Dust Men burst through the far wall. Let loose with Grenades and Hammers. Your platform may be destroyed and you'll find yourself on the ground without unlimited energy. If so, take cover behind a concrete barricade and use your Lightning Bolts. You may face a trashbot as well – you know how to take them down: target their arms first.

Finally, you'll receive a distress call from Zeke. You have to get up to the generators on the roof of the prison. If you've previously done the Good side mission, Containment, you'll have been up there before. From the prison yard, make your way to the wall to the left of where the Dust Men broke in. Climb a light pole and jump to the walkway.

Circle around the prison, staying up on the walkways, until you reach one of the high walls of the main prison with a large section falling out. Jump up to the ledge to the right of that broken section and make your way around the wall until you find a place with lots of windows you can climb. Climb up and circle around to a tower, then climb up to a roof. There will be Dust Men up here, so dust them.

To the prison yard
At one side of the roof is a set of broken walkways. Jump up from the first broken section to the wall and across to the other section of walkway. At the end of the walkways, look down to see broken pieces of the wall sticking out. You will have to quickly jump and glide your way around the wall. Never stop moving because the broken bits will fall off as soon as you land on them.

You will soon come under fire. Find a metal beam to land on (they don't break away) and take out the Dust Men. Jump across to a brass pipe and climb it to another pipe from which you can jump to the next set of platforms. Jump across three platforms and some beams to reach another brass pipe you can climb.

Jump up to the ledge and go back the other way, jumping from beam to beam. Work your way around to a set of barred walls with fire burning behind them. Climb the ledges over the barred walls to find the generator platform. Charge the big control panel on the back wall, then climb a beam to a broken walkway and get higher on the roof. You'll have to dust a few more Dust Men up on top, then work your way down to the prison yard. Watch out for machine gunners up here and take them out from on high.

Find Alden
When you reach the prison yard, you will once again have an electrified walkway you can use for unlimited energy. There are actually two – one to each side of the yard. When one is destroyed, run over and use the other.

Spam Grenades, Hammers and Shockwaves until your platforms are destroyed. Make sure to heal every few shots by recharging from the platform. You'll face at least three trashbot Conduits. When the wave of enemies finally peters out, you'll be told to return to the prison. Walk toward the back of the yard to end the mission with a cutscene.
