In "Vertigo", you must destroy all the choppers within the mission for Flyswatter. This can easily be achieved on the easiest difficulty setting with a good Co-Op parter, or even solo. In "Arctic Recon", you are tasked with completing the mission in under 3:30 in order to obtain dr0n3d. There are also specific achievement tasks you must complete during these two missions. Lastly, a Veteran completion of "Light 'Em Up" will unlock both Siege and Lights Out in one playthrough. If "Special Delivery" is completed on Veteran right away, you will unlock Handle With Care and Deliver This upon mission completion.
If you complete "Vertigo" on Veteran right away, you will unlock Apex and Pinnacle. If you complete "Arctic Recon" on Veteran, you will unlock Stay Frosty and Sub Zero in one playthrough. Each mission has two difficulty-tied achievements, which are stackable. You will probably need a minimum of 3-4 playthroughs on each of the 4 new missions in order to get all the achievements. Make sure your tank does not receive any damage during the course of the mission in order to unlock Not a Scratch. When you get to the beach, have the tank creep up slowly in order to help take up the enemy tanks. In "Iron Clad", simply have your partner who is controlling the tank stay back, while you move forward and kill everyone on the road. There are a total of 6 helicopters to take out in this mission, all which can be shot down with the sniper and the predator drone.
In "Killswitch", the player who begins on the catwalk as Sniper-Support will be able unlock Helipocalypse for both players. Likewise, if you complete "Killswitch" on Veteran immediately, you will unlock One-Four-One and EMPressive. If you complete "Iron Clad" on Veteran from the start, you will unlock Don't Tread on Me and High Roller together. You will probably need a minimum of 3-4 playthroughs on each of the 2 new missions in order to get all the achievements. Having an extra person will move this along a lot faster. The waves go beyond this, but it's just the 15th you need to get to (no need to complete). In this mode you're going to have to play each of the 16 maps and get to wave 15. So with that extra gun on the field, it'll help a lot. Some of these will be very hard with just you. First play the maps on a easy difficulty to get a feel for it all. You'll have the chance to get 3 stars in each mission, and to get all the achievements relating to this mode, you're going to have to play and complete each one on Veteran. This is exactly the same as MW2's Spec Ops. It's up to you where you which one you start on as both will take time and have it's challenges. Each mode has a total of 16 maps you'll need to play. This is where the bulk of your time will be spent. Though to save yourself having to do this, please see the guide below for more details. Don't worry if you miss one while you play, as you can return to any of the previous levels and obtain it again. Some will be in plain sight, while others maybe a little trickier to spot. There's a total of 46 Intel collectables throughout the story based missions.
Just carry on with the story and you can come back to them at any point on a lower setting to make it easier. If any of them are proving to be hard on that difficulty, do not worry. Now if you're playing through on Veteran first, some of these may prove a little difficult. There are many misc based achievements, which you can only obtain during certain missions. So it's a lot easier than the previous installments. It's pretty much the same if not a little worse than MW2's. So your best bet is to start on the hardest difficulty.Call of Duty is known for its Veteran difficulty but don't worry about this one. There's a lot of "Complete this mission" based achievements and another half of them are linked to the Veteran difficulty. If you're looking to compete this game in one playthrough, you're going to need to head straight onto the Veteran difficulty. Overall this game isn't the hardest 1610 to get. The campaign shouldn't take more than 5-6 hours to complete, and most of the hours will be put into the Spec Ops modes. Overall the game isn't all that bad, but it depends on your history with the other call of duties and its Veteran difficulty. The game takes place right after the end of Modern Warfare 2, so you'll be right in the thick of things.
Welcome to the 3rd installment of the Modern Warfare franchise. Minimum number of playthroughs needed: 1 playthrough
