You must complete all of the following missions on the Hard difficulty:
Fire From the Sky
Hit and Run
Drop 'Em Like Liquid
The Eleventh Hour
Please note that you must complete the first two missions (Operation Exodus and Fire From the Sky) to unlock the third mission (Exfiltration). Once you complete the third mission, another two missions (Hit and Run and Drop 'Em Like Liquid) are unlocked. Once you complete those two missions, it will unlock the last mission (Eleventh Hour).
Good strategies for the missions:Operation Exodus
: Surprisingly easy mission even on hard. Make sure of the partners has a Javelin at all times. I recommend one of the partners also having an SVD to easily kill the enemies from range. Team work is key here. Make sure you and your partner are in close vicinity because the enemies advance quickly at times.
If you can complete the mission without losing any Humvees, you will acquire this achievement:
The Car Lover achievement in Battlefield 3 worth 43 pointsComplete the mission without losing a humvee in Operation ExodusFire From the Sky
: Please watch this video (http://www.ign.com/videos/2011/11/02/battlefield-3-how-to-fl...
) to understand more about flying.
In the first parts of the mission, the pilot should just do his best to hover around your allies which are on the ground while the gunner of the helicopter uses thermal mode and takes out enemies on rooftops and in the streets below. The pilot can also fire rockets while the gunner shoots. You will want to stay about 50-70 feet above the ground (the indicator is on the right side of your screen).
For the latter portions of the mission with the AA guns and the BMP's, your best option is to stay as far back as you can while still staying in the range so your pilot can fire heat seekers at the enemy vehicles. I would recommend having your friend lock on and fire a heat seeker and while it is reloading, you can move in a little closer for you as the pilot to fire the 14 rockets and for the gunner to fire with the machine gun.
If you complete this mission without having to put out a fire in the helicopter, you will earn this achievement:
The Untouchable achievement in Battlefield 3 worth 35 pointsComplete the mission without using the fire extinguisher in Fire From The SkyExfiltration
: The first portion of the mission is the stealth portion.
If you complete the first portion of this mission without alerting any enemies, you will receive this achievement:
The Ninjas achievement in Battlefield 3 worth 50 pointsReach the VIP without setting off the alarm in Exfiltration
Once outside again, you will move down the streets killing numerous enemies on the ground and buildings. At the first ambush where the enemy fires an RPG at you, I recommend staying the in the back of the street where the large storage container is. At the first ammo crate, there is an SVD. I recommend one of the players picking up the SVD.
You will continue to move down the street and hang a right about 100 yards down the road. The Humvees will follow and open the gate to the new area. Another ambush will occur. For this portion, I recommend staying off to the left side, behind the white van where the ammo crate is. From here, guys will spawn in various floors of the blasted open buildings. The enemies will also spawn on the ground in front of you and to the northeast of your position behind the white van.
If you get caught up in this portion, I recommend tossing grenades into these areas to flush out enemies. After the area is clear, you will move onto the .50 cal and while moving along, another ambush occurs and the humvees will move down the road while enemies fire at you from all angles. I have played this mission numerous times and I don't believe you can die on this portion.
Once the Humvees stop, the player in the front humvee will be given C4. Instead of immediately placing the C4 on the door, place 1-2 on the van on the right side and 1-2 on the left side where the low wall is. Make sure to do this step quickly. Once near the wall to be blasted, wait a moment and then explode the C4. Replenish your C4 and blow up the wall. No enemies door come from the door you just blew up. For the next portion, around 3-4 enemies waves will attack you from the left and right combined.
Eliminate them and move back to the humvees. After another ride in the Humvees you will end up in another firefight. In this portion, my suggested spot is where the allies are stacking up in the room where Hamid El Zakir is. (the person you rescued in the beginning). After the long firefight here, a helicopter will pick you up.Hit and Run
: The mission is fairly easy so I won’t explain it as much as the others. In the first portion after the initial ambush, make sure you look to the scaffolding outside on your right because enemies due stack up there and snipe you.
In the final portion of the mission, you will acquire a vehicle. You cannot die in the vehicle. If you need help and once you reach the garage portion of the mission without either players going down, you will earn this achievement
The Push On achievement in Battlefield 3 worth 54 pointsReach the garage without going into man-down state in Hit and RunDrop ‘Em Like Liquid
: This is a sniper only mission. For more info, please refer to the guide on TA:
The Bullseye achievement in Battlefield 3 worth 89 pointsReach and save the hostages without alerting any enemies in Drop 'em Like Liquid
You will have to have synchronized shots among you and your partner. Communication is key. Some system like 3 2 1 Go is a good system for the synchronized shots. Always deploy your bipod for more steady shots and always go for headshots.
Please be aware that the Bullseye achievement is somewhat glitchy. Certain aspects like ‘runners’ can void the achievement, I believe. My friend and I had one runner (an enemy who is shot and runs to alert other enemies) and we still didn’t get the achievement. The Eleventh Hour
: The mission is fairly simply. You will move through the subway killing enemies. Once you pass the construction equipment behind the first train, a notion will occur that the bomb is active. One of the player should grab his 870MCS or M1014 and move up very quickly towards the bomb. While he pushes up, the other player should eliminate the surrounding enemies.
Please refer to the achievement guide on TA:
The button sequence for the bomb is: A LB RB RT RS B A LB RB RS.
Note: The RS symbol in the sequence requires you to click the stick, not to move the stick. Wait for the next button to pop up on the screen before you move onto the next one. Also, when one player is diffusing the bomb, enemies will be advancing so the second player should be ready for another wave.
If you are struggling, complete the mission first on hard and then retry the mission on easy or normal and easily complete the bomb sequence.
After the subway sequence, you will move into the French Stock Exchange area. Move through the building normally looking for enemies around all corners. Once you reach the actual stock portion (the flooded area) watch out for enemies on the ground and on the balconies above.
Then you will continue on into the next room. One of the players should push up to the square pottery item in the middle of the room while the other stays behind the limited cover of the small door room. The enemies will mainly spawn and jump down from the offices on the left.
After this confrontation, move to the door on the right side of the room. Both you and your co-op partner need to stack up. Immediately after breaching, the high-valued target will grab your partner. The button sequences are randomized for the two partners. One partner will be grabbed by the high-valued target and must tap his selected button while the other partner will see another button appear on the screen so as to shoot the target.
The mission is complete here and you should get your achievement 50G Army of Two (complete all of the Co-Op missions on Hard) and 30G Two-Rah (complete all of the co-op missions).
