Act II: Exodus

Locate and Neutralize the Anti-Aircraft Guns

For most of this mission, you'll be assisted by a tank that can provide cover fire. However, you'll have to designate where it shoots by selecting targets with your laser (activate it by tapping right on the control-pad, then confirm a target by pulling the right-trigger.) You can target practically anything, such as homes or groups of enemies, then watch with glee as the tank mows down the combatants.

For the most part, you should hang back behind the tank and let it take out the targets you select. This will keep you out of harm's way, though if you do draw fire, simply reposition yourself and use the tank as a shield. On occasion, you may have to push forward, ahead of the tank, toward the sergeant (who's marked with the "follow" icon), triggering the next segment. Once you have, you can then pull back again and resume the same strategy.

Intel (1/3) When you reach the Garden Villas apartments on the left side of the street, look for a small office just past the main sigh--inside you'll find the intel on a desk.

Before long, you'll encounter a fortified checkpoint, just before an overpass. Again, hang back and target the various buildings and groups of enemies with the targeting laser and let the tank clear most of them out, leaving you with clear-up duty.

Intel (2/3) At the checkpoint, check inside this small office on the right for another piece of intel.

A short distance past the checkpoint, you'll begin crossing over a bridge. Makle sure to select targets for the tank to target as you cross!

Intel (3/3) After crossing the bridge, check the second level of the second house on the right to find this intel.

Further up the street is a large mansion you'll have to enter in order to exit out a side door on the left side. Focus the tank's fire on it first, then enter through the garage and clear it out. Now enter the house proper via the left door and continue to follow the left wall to the exit (in the room with the billiard tables).

Back outside, you'll spot two vehicles: one ahead, another to the left. Target each with your laser to star a bombing raid, taking them out.

Go to 4677 Brookmere Road.

After the bombing raid, follow the dirt trail on the left back to the main street, and cross the bridge to the burning building.

Retrieve Intel from the 'Panic Room' at 4677 Brookmere Road

Don't worry, there's no more enemies to deal with. Enter the burning building and head upstairs. Grab the briefcase by the corpse in the panic room to complete the mission.
