The police are trying to capture Alden. Head northeast to the objective marker on the map. When you arrive, you'll find a dead officer and will read the shadow of Alden. Follow it. Stay on the ground, and after a couple of turns you'll come across a mob trying to exact some vigilante justice.
For Good Karma, shoot the man down. For Evil Karma, follow after Alden's shadow. (This Karma Moment will now pop up with great frequency in the game.) Once the Karma moment is done, turn and climb the lamp post where the man was strung up. Find the gun turrets in the fortress across the street and take them out with Precision or Hammers. Recharge from the HVAC units on the roof behind you and follow Alden's ghost into the fortress.
You have to fight your way through hordes of enemies as you twist your way through the fort. There are plenty of energy sources, so feel free to use Hammers and Grenades aplenty. After you get behind the row of machine guns, Alden's ghost will climb a ladder and walk along a ledge. Climb up after him and then climb the pipe to a walkway.
Fight the trashbot[edit]
Make sure you fully charge yourself at the fuse box on the walkway; you're about to fight a Dust Man trashbot Conduit. Follow Alden's shadow to the center of the park and watch the trashbot rise from the ground. The key to defeating a trashbot is taking off its arms. It has three attacks:
- Machine gun. When this starts firing, leave aiming mode and run in circles ahead of the fire.
- Meteor blast. This large, flaming rock shoots out of its chest. It is easy enough to avoid simply by running sideways.
- Ground slam. This causes a blast effect in a small radius around the bot. This is not a problem as long as you stay way out of range of the bot.
There are lots of lights around the park you can use to recharge. Keep up fire on the bot's arms (use Lightning Bolts) until both arms are destroyed. It then loses its machine guns and will, briefly, fall to its knees. Stick it with a bunch of Grenades. If it does get up, all you have to worry about is the meteor and ground slam – both easy to deal with. Keep sticking it with Grenades until it blows up.
