The Price of War: Complete the single player campaign on Hardened or Veteran Difficulty.(90)

Notes: You are going to DIE...and die alot you shall. Take notes from the achievement above ^ Slow is the way to go. Try not to become overly frustrated and take it one checkpoint at a time. Enemies often come or sit in the same spot so if you keep dying, figure out where your being hit from and take the necessary procedures to move forward. Go SLOW.

First Day of School: Complete "S.S.D.D" and "Team Player" on Veteran Difficulty.(25)

Notes: First two missions of the game. Its best not to try and sneak up on any enemies. Simply shoot them and don't try and be a hero.

Black Diamond: Complete 'Cliffhanger' on Veteran Difficulty.(25)

Notes: Third mission of the game. Just follow Soap's orders and try to stay hidden. If you are spotted it will become extremely tough to survive. Once Soap is captured you will need to fight your way through to your get away. He will be yelling at you to hurry up but there is no time limit. Take your time and pop off one enemy at a time to work your way forward.

Turistas: Complete 'Takeover' and 'The Hornet's Nest' on Veteran Difficulty.(25)

Notes: These are missions five and seven. These were some of the hardest missions in the game - the alley ways are tight and it is easy to be pinned into a corner. Can't stress enough how important it is to move slow. Look for the area least traveled as well. You do not have to go up a path that is in front of you, often sneaking around the long way will save you many lives you would have otherwised thrown away. On Hornet's Nest be sure that after you miss the jump to sprint and don't worry about shooting any enemies. RUN FORREST RUN!

Red Dawn: Complete 'Wolverines!' and 'Exodus' on Veteran Difficutly.(25)

Notes: Wolverines is a long mission so be sure you have a large time period laid out before you start. Don't wanna be in the middle of it when momma is yellin to come get your dinner. Eventually you will be presented with a Predator Missile - You have unlimited uses for this until it is shot down so FIRE AWAY! On the Exodus be sure to use your laser designator to allow your Striker to clear out anything in the area you wish to move too. Be careful as it can also kill you.

Prisoner #627: Complete 'The Easy Day..Was Yesterday' and 'The Gulag' on Veteran.(25)

Notes:'Easy Day' Be sure to shoot the terrorists and not the civilians. There are several exploding barrels you also must look out for. 'The Gulag" you begin with a sniper rifle, before going inside be sure to pick up an enemies weapon that is close quarters ready. The mission ends when you drop through the hole in the floor so it is possible to just run through several enemies and complete the mission.

Ends Justify the Means: Complete 'Contingency' on Veteran Difficulty.(25)

Notes: This mission does become timed at one point so you need to make your shots count and keep pressing forward diligently. You will have access to a predator missile and once again it does not have a limit to it so use it freely. Try and take out as many enemies as possible with each shot by aiming at nearby explosives i.e. vehicles.

Homecoming: Complete 'Of Their Own Accord', 'Second Sun', and Whiskey Hotel' on Veteran Difficulty.(25)

Notes: Of their own accord - Be sure to pick up the sniper rifle and pick off the assault soldiers, then pick up the javelin and take out the tanks. Stay in cover and hide when the choppers come in. Use the mounted machine gun later in the stage to kill the infantry.

Queen takes Rock: Complete 'Loose Ends' and 'The Enemy of My Enemy' on Veteran Difficulty.(25)

Notes: At the later state of loose ends you are ambushed, hold on to your flash bangs to use at this moment as they will come in very handy. Remember to use flanking maneuvers throughout the game, especially in the latter part of this mission. In the 'Enemy of My Enemy' you need to try and sneak around the two groups of soldiers who are fighting each other. You can make it through a large portion of the map by not engaging the enemy and allow them to fight it out amongst each other.

Off the Grid: Complete 'Just Like Old Times' and 'Endgame' on Veteran Difficulty.(25)

Notes: You have made it to the final two stages of the game! Follow orders and once you get to the boat chase focus on driving the boat. Only fire when necessary

Pit Boss: Run The Pit in 'S.S.D.D' and finish with a final time under 30 seconds.(10)

Notes: 1st if you are doing this by yourself then you must complete it in the single player - not the Special Ops. The key is knowing that you do not have to actually finish in under 30 seconds. You receive bonus time by not killing any civilians and having a high amount of accuracy. So if you are running with an assault weapon then barely pull the trigger so that only 1 bullet comes out. May take you a few tries before you know where all the enemies are so I suggest starting off by going super slow and taking in all the enemies and civilians and their locations. Figure out where you want to move after each hit and in what order you wish to take them out. Get a Gameplan! Pit Boss Achievement Walkthrough

Ghost: Plant the C4 in 'Cliffhanger' without alerting or injuring anyone in the blizzard.(10)

Notes: Recommend you change your difficulty level to Recruit before doing this. Makes your life much easier! Pay attention to your heartbeat sensor and restart the mission from the last checkpoint if you are spotted.
