The first few cannons
The first gun you need to destroy is right in front of you. Take it and its guards out. Destroy the water towers and HVAC units over to one side, and you'll find a Dossier, Gamma Regulator and Power Pip inside. Go up the stairs to the west to reach the second cannon and destroy it.

Now head west down an "alley" into the face of a mini-boss robot and rocket troopers. A Guided Fusion may be just what the doctor ordered for this situation. The third cannon is at the end of the alley. Go down the stairs and take out cannon number four. On this roof level, go back in the corner behind a water tower to find a Body Upgrade.

Down one more level and you have a whole mess of robots and soldiers and a chopper. Get close enough to the chopper that it stops using rockets and starts throwing grenades. You can pick these up and throw them back to make it go away. You can then concentrate on the mobs and destroying the fifth cannon.

Songbird
One of your helicopters comes in and makes a bridge for you. Cross and take out the rocket troopers firing at you; then, clear out all the robots that run onto the roof. You can pick up a Boost in the water tower in the front corner of this roof. When soldiers blow through the fence above you, move up a level for a boss fight.

Your opponent is ../Songbird/, herself a reformed criminal now treating you like one. Serves her right if you unload some Targeted Fusion on her. Her sonic attacks are strong; but, easy to avoid since they have a narrow arc. After she's down, another makeshift bridge appears to take you to the final cannon. Cross, pick up an Audio Log beside the water tower; then, take out the cannon and watch the cutscenes.
