Use melee on the guy in front as you start. Enter the building to the right and melee the bad guy standing with this back to you in the opposing doorway. Exit and eliminate the bad guy in the building ahead. Follow Mother and crawl through the tunnel he opens up and after crawling through, shoot the enemy and then continue to follow Mother.
In the next building, take out the guy inside and then continue out the next door. Stop when you reach the low wall. Mother will halt here, behind the wall you’ll see two guards patrolling on the balcony, you’ll out your secondary weapon, here you can get an achievement. If you can kill both of these bad guys with one shot you’ll unlock it.
Note: For killing both these guys with a single shot, you’ll unlock the achievement/trophy ‘Double Header’
Go through the building and you’ll see another three guys through the window, if you missed the achievement on the previous attempt, you can take two of them down at once here. Mother will help you out with any that you miss. Head over to the marked door and breach it. Again, kill the four enemies inside with headshots to unlock a new breach option.
Note: If you can headshot all four guards you will unlock the next breach option – Door Knob charge.
Once inside, head out the opposite door. At the second cover spot, take out the baddie on top of the boat in front and to the left. This will cause another group of snipers to spawn in the area ahead. When prompted, pull out your LTL and use the laser to target the building indicated.
After the fireworks, follow Mother up the road until you reach the next set of cover. Take out any enemies in the immediate area (there should be 4-5 of them – if you have trouble seeing them, look out for the flashlights) and then continue forward eliminating baddies as you go. More will appear from a corner to the left as you move forward and another group will appear from the bell tower to the left. Once all the enemies have been cleared from the area,enter the area beneath the bell tower and breach the door... Predictably, there are four enemies in here to take down.
Note: If you can headshot all four guards you will unlock the next breach option – Flex Linear.
Exit the opposite door and back outside again, continue onwards until you reach the marked alley. Work your way through here, watching out for enemies that appear on the balconies at the back left and a good number of bad guys at ground level too who will use the low walls on either side as cover from which to attack you. Try to stay at the gate and pick them off one at a time, waiting for them to come to you, when no more decide to come out in the open, move in and hunt down any survivors. When it’s clear, follow Mother to the gate at the far end.
After the gate opens, follow him through the upside down bus and then take cover behind it. Kill the three enemies in the area (one directly across from the back of the bus and the two more that enter the area from the other side. When they are dead, follow Mother up the nearby ramp. From here, pick off the enemies in the courtyard below and from the roof at the far side over looking it.
Clear the area as more guards arrive and be sure to keep an eye out on the left hand balcony as an enemy will try to pick you off from here if you are not careful. Continue to follow Mother through the area, taking out the enemies as you go.
When you reach the flooded market area, take cover behind the low wall to the right as you enter and take down the baddies as they enter from the alley in front and to the right. Take them all out and when he moves, follow Mother through the area to the right. Eliminate the next group of enemies that appear and then continue down the passage to the right of the building in from.
When you reach the corner, you’ll be ambushed again, so take out the enemies that appear, keeping an eye out for the balcony in the left. After killing a few at ground level, several enemies will appear on the balcony on the right hand side of the street and an RPG toting baddy will attack from a roof top to the left. Once they are all dead, continue to follow Mother. Up the next alley, stopping to take cover and eliminate hostiles as you go.
Once the area is clear of enemies, breach the door at the top of the stairs. Follow Mother across the area to the next building and climb the stairs here. Open the door at the top to complete the mission.
Note: At this point you’ll earn the achievement/trophy ‘Rain of Terror'.
