Army of 2
Easy sniper, assault rifle, and pistol achievements
In the training level after the back-to-back lesson, you will be told to run around the
corner. There one of you will bleed out. Do not have your partner heal you. Instead, sit
there and shoot all the guards. You will not die and their bullets will be ineffective. A
total of about 80 enemies will appear. When they stop, restart from the checkpoint and
repeat the process until you get the achievements. Note: When your health meter
reaches zero when bleeding out, your character will fall back then get back up.
Easy "Fission Mailed" achievement
Keep restarting the Afghanistan level. Four or five martyrs will show up during the
back-to-back section. After that, if you restart the checkpoint, one will appear if you
boost up onto the compartment and kill them. Make sure to aim for their chests and not
their heads. You can only get the achievement by blowing up the bomb packs on their
stomachs.
Easy "Fear Is The Mind Killer" achievement
Get on one of the gun turrets you encounter, and keep firing. This will fill the Aggro
meter and keep it full for the one minute requirement to get the achievement. This is
easier to do during the second mission.
You can get this achievement with the M134. As soon as you have it, go to the Afghanistan
level. After you pass the first wave of enemies, you must go through a tunnel. If you are
playing alone, keep your AI behind where he cannot shoot enemies. Run pass the first set
of sand bags, and get to the second set in front of you. Use the M134 to shoot any
incoming enemies. Then, just keep shooting until you get the achievement. If you are
playing in Co-op mode, do the same thing; one player stays behind and the other one
shoots. Restart to the last checkpoint if the other player also needs the achievement.
Easy "Big Boom! Big Bada Boom!" achievement
An easy way to get this achievement is to shoot while you are dropping down by parachute.
Purchase the RPG, and play the mission where you are trying to land on the Navy ship. At
the bottom you will see three guards. Shoot at them as soon as you can and before they
disperse. Once you kill them, restart from the last checkpoint. Repeat killing the enemies
until you get the achievement.
Easy "One Shot. One Kill." achievement
An easy way to get this achievement is to shoot while you are dropping down by parachute.
After the first level when you are parachuting down, take out your sniper rifle, and start
shooting. Once you kill all enemies and before you land, pause the game, and restart from
the last checkpoint. Repeat killing the enemies until you get the achievement.
All primary weapons
Successfully complete the game on the Recruit or Contractor difficulty to unlock all primary weapons (assault rifles, shotguns, etc.).
Metal Gear Solid reference
The MSG-90 sniper rifle has a barrel type named "MGS Sniper-Wulf", which is a reference to the Sniper Wolf Boss in Metal Gear Solid.
Easy "L'abattoir" achievement
Go to the China mission, and have your AI hold position. Run up the hill to get full Aggro, and kill all the enemies. Shoot the bridge, then run back down the hill. Get full Aggro again, and kill all the enemies. Reach the check point, quit, and restart the mission. You should get the "L'abattoir" achievement in approximately fifteen runs of the mission.
Intel locations
The following is a list of all 14 briefcase locations. You get a cash reward for picking up each briefcase. They can only be collected once, and disappear in future playthroughs once they are collected. You can check "Objective" in the pause menu to see how many briefcases you have collected for the level. Collection is accumulative; you do not have to collect all briefcase in the first playthrough. Afghanistan 1. Behind the first M-11 missile is a small uphill path; follow it all the way to the end to find the briefcase. 2. After encountering the first heavy armor guard in the mission (a cutscene plays showing him walking out of a door), kill him and all the guards, and search the platform area. The briefcase is up past a short set of stairs at the back of the platform. 3. In the area just outside of Brian Hick's cell, go all the way to the back to find the briefcase. Iraq 1. Right before ascending the ladder to take out Ali Youseff's Lieutenant's Helicopter, look around at the bottom of the ladder to find the briefcase. 2. When you are asked to call in the air-strike on the bunker, run to the tent nearest to the huge wall dividing the area (there are some sentry towers near the wall). The briefcase is on the side of the tent facing the wall. 3. In the final area of the mission before meeting Ali Youseff, there are some metal platforms with guards on it. Kill them all, climb up the small steps to the second level of the platform, and then the ladder to the third level to find the briefcase. Aircraft Carrier 1. On the main deck of the ship after you land, run behind the control tower and to the right to find the briefcase on a platform on the side of the ship. 2. In one of the hangars, you have to operate one of the planes to blow through a door (a heavy armored guard appears once the door is blown). Search around the wall closest to the door. The briefcase is behind some missiles. 3. In the final hangar, after activating the missiles to sink the ship, look around the back right of the hangar to find a basketball court. The briefcase is behind the basketball hoop closest to the hangar wall. China 1. Once you arrive at the dam, go up the stairs towards the first control panel. Look across the dam to see a similar structure directly opposite. The briefcase is there. 2. Once you arrive at the village, co-op snipe the two guards, and take the right path. At the first house you can enter on the path, head to the second floor to get the briefcase. 3. After the only back-to-back sequence in China, do not enter the factory. Search outside near the back of the factory (it is behind a dump) to find the briefcase. Miami 1. After the gates to the luggage area are opened, you have to run to the second floor to operate a control panel. There is an office right before the control panel. Search around the back of the office to find the briefcase. 2. On the third floor of the SSC tower where you have to jump onto the lift, ignore the lift, and keep running forward to the back of the floor to find the briefcase. It is directly opposite and across to the staircase that you came up on.
