Complete Bishop Takes Rook in Campaign on any difficulty
Very simple, just complete the first mission.

In Blood Fued, reach the Guild meeting without ever breaking stealth
In the beginning of the mission, take out the guard by the river and then head towards an opening of the river on the left hand side. Swim through the tunnel and turn right after you exit, going towards some stairs.











After heading up the stairs, keep left and follow the scaffolding. Take out the enemy nearby then climb up to the open window on your right. Turning right once inside to find a locked bar door, this is the bell tower entrance. Climb up the ladder.





























Once you've climbed up and sniped Yannik on the yacht, jump out of the bell tower into the water below. then follow the same route that we took to get to the bell tower back to the starting area.

After a brief cutscene, enter the restaurant via the left alley, then go left in the vent and take out the guard in the restroom.











Lure the remaining 2 guards into the restroom by making a sound or letting them see you enough to get suspicious and back away in the restroom. Kill them when they get close. Then make your way up to the stairs, staying quiet by crouching. At the top of the stairs, wait for the guard on your left to face away and the guard on the right to walk away, then kill the one on the left and walk through to the door on the left. Poof achievement :)

Perform 10 takedowns in Campaign
During the second mission of the campaign, you are able to silently takedown enemies. Slowly make your way around the map whilst killing off as many people as you can with only takedowns. Remember that you have traps to distract the enemies and can lure them out using the stealth mechanic. Good luck.

Complete Blood Feud in Campaign on any difficulty
Very simple, just complete the second mission.

In Most Wanted, perform 5 takedowns on guards in the gala without being spotted
This can be done right at the start of the mission. I don't think you need to sit with Sev prior but I did anyway. To begin, head over to the coat rack and get that guard first.











Then head back out the same curtain and turn left to find another 2 guards facing the West Wing. Lure them into the curtained off area and take them on one by one. Move the first body away from the curtain they come from.











Next ones are inside the West Wing area. Follow the door on the left towards the employee only areas and exit into the West Wing through the open door. Here you can mark the final 2 guards.

Get 2 Kills with a single remote controlled Throwing Knife from at least 50 metres away in Campaign
I got this on the 'Escape the Black Site' objective during the 'Most Wanted' mission. Before you enter the large computer room (the one you stealth through, if chosen, with the large windows either side of the room), head back until you hit a metal shutter and equip your explosive throwing knife. Aim just under the door frame and steer it down then back up until the catwalk where 2 enemies shoot at you.




















A second opportunity presents itself towards the end of the mission in the main gala hall. Once you come out into the West Wing, prime the knife and throw it over the stage. Aim down and towards the group of 4 enemies in the centre of the room.

Complete Most Wanted in Campaign on any difficulty
Very simple, just complete the third mission.

In Hunting Season, complete every POI (Place/Point of Interest) on the Tac Map
This is rather simple, just follow the map and discover everything before destroying all the Scud Launchers.

Get 5 or more kills with a single Scorestreak in Campaign
Straightforward achievement here, during the mission Hunting Season, you get access to a Tac-Map. Talk to Gladney and receive the Helicopter Crash side mission and then head towards it, it is southeast of the camp. Once you arrive, take care of the enemies then pick up the Stealth Bomber scorestreak that Bannon gives you and eliminate 5 enemies with one use. Should come easy if you didn't kill many or any enemies at all during the second wave of attacks.

Complete Hunting Season and The Cradle in Campaign on any difficulty
Very simple, just complete the fourth and fifth missions.

Complete Emergence in Campaign on any difficulty
Very simple, just complete the sixth mission.

Get 5 Headshot Kills during a single use of the Adrenaline Stim in Campaign
Midway through 'High Rollers' you will take back control of Case and be fighting through the casino. Just before the enemy shield elites come up, there will be a stash on your left before turning the corner. Check the stash for a singular Adrenaline Shot and be ready to use it on the upcoming enemies that come down the stairs and around the pillars. Do not try to kill the shields, they take too long to kill with a head shot. Remember you can move around during this too so get closer if you need to if you can't see due to the screen distortions.

Complete High Rollers in Campaign on any difficulty
Very simple, just complete the seventh mission.

In Ground Control, crush 25 enemies while driving the tank
Towards the end of the mission, you'll take control of a tank on the tarmac. Get in and just run over as many enemies as you possibly can. You are sure to get this if you follow large groups of enemies then pick off the remaining ones in the area before moving on. If you do it decently enough, you'll get this just before the final stretch to Gusev's plane.

Just remember you can destroy the majority of the environment around you, so if you see a large group behind some stuff, run that stuff over.

Complete Ground Control in Campaign on any difficulty
Very simple, just complete the eighth mission.

In Under the Radar, have the SAM target itself and the helicopter
After taking control and going towards the main base, find the middle desk guard for the Warhead area and knock him out, then put him in the locker. Hack the computer and input the following codes;

ORION >> TARGET >> (Hack SAM Site) >> ICARUS >> CODE




















After this, go ahead and disable the RADAR however you'd like. Then disable the security feed, watch the cutscene and when you're in the chopper as Case, do not shoot the helicopter.

Complete Under the Radar in Campaign on any difficulty
Very simple, just complete the ninth mission.

Complete Separation Anxiety in Campaign on any difficulty
Very simple, just complete the tenth mission.

In Checkmate, destroy the APC using an RC-XD
While defending the safehouse from an attack by the front entrance, an APC will eventually appear. You need to weaken it and then blow it up using an RC-XD. To weaken it, I suggest using the nearby rocket launcher twice, then shoot it until it starts to ignite on fire. Then whip out the RC-XD and blow that guy sky high.

Complete Checkmate in Campaign on any difficulty
Very simple, just complete the eleventh and final mission.

Complete the Campaign on any difficulty
Congratulations, you have completed the Campaign.

Complete the Campaign on Veteran difficulty
Congratulations, you have completed the Veteran Campaign.

I recommend going through the Campaign on Recruit or Regular before attempting Veteran. This is just to get the 'lay of the land' so to speak and understand the twists, turns and enemy spawns.

It is also recommended that you complete the Gear and Guild upgrades as much as you can so you can be better equipped and prepared to complete this achievement. Of course, a max safehouse is the best safehouse, so gather as much money as you possibly can and upgrade everything. If you feel confident enough you can do this without any upgrades but note that it will be much harder.

Purchase all Safehouse and Player Upgrades in Campaign

Complete all Safehouse Puzzles in Campaign
The following states how to complete this achievement;



The Piano Puzzle

• Get the Blacklight
  
• Find the 5 numbered musical notes on the walls of the same room and note them down. The order is typically Mn >> Pe >> Cn >> Ao >> Pe
  
• Play the correct notes in the order shown in game on the piano (The notes show up on the top of the piano via Blacklight, they correspond the the key below it).
  
• A door will open to show success.

The Boiler Room Puzzle

• Go to the Basement/Boiler Room
  
• Turn the middle boiler valve twice
  
• Turn the left fuel valve once
  
• Press the right pilot button once
  
• Turn the middle boiler valve twice
  
• A green blinking light will signify success

The Keypad Puzzle
Note that the combination changes every 5 tries.

• Enter the Piano room secret door
  
• Decipher the pass code using the Blacklight
  
• The door will open showing success.

The Computer Puzzle

• Enter the door and find the computer by keeping to your left.
  
• Input the correct order using the code words provided.
  
• The computer will boot you out when done correctly.

The Lockpick Puzzle

• Head out the computer room and turn right, then into a door on your left.
  
• Pick the lock on the locked door in front of you.
  
• Pick up the key on the table in the middle of the red lit room.

The Radio Puzzle

• Leave the Lockpick Puzzle room and turn right at the intersection to find another locked door on your left, use the key on it.
  
• Tune the radio next to the TV. This is simply just using WASD to match up the wavelength.
  
• The radio will now announce what the code is to the safe on the 1st floor of the house via location clues. Listen closely and find the numbers given by the man on the radio.
  
• The pass code goes in the order of; Sofa >> Purse >> Calender >> Flag
  
• Note down which numbers they are. If you cannot find one of the numbers but are sure on at least 3, you can brute force the code to finish it.

Now head upstairs to the safe, which is located by going to the far left room when going to the 1st floor via the front door flight of stairs and enter the code.

Get 500 Eliminations in Multiplayer
This will come with time, just keep playing the gamemode and you'll eventually achieve this. You can check your progress in the stats menu.

Win 25 Multiplayer Matches
Again, this will come with time. Just keep playing and you'll eventually get it.

Get a Double Kill with the RC-XD in Multiplayer
Best way I've found to do this (as funnily enough I did this in the first Beta) is to play Domination, or a game mode that provides an area of defense, such as Domination or Hardpoint, where a group of enemies will likely be. Just survive long enough to get the RC-XD, use it in a place where it won't be destroyed immediately, and rush in finding 2 enemies within close range.

Alternatively, there is the luck method. Just put on the scorestreak and keep playing until you get it. Focusing on the achievement it self will likely put you through much more pressure than necessary, so I would recommend doing it passively with the other achievements listed.

Get featured in the Best Play 3 times in Multiplayer
This is easier than you would think, focus on multi-kills or get into the enemy spawn and wreak havoc.

Keep note that scorestreaks do not seem to count towards this, only gunplay does.

Complete the Training Course in Multiplayer
During the introduction to Multiplayer, you will be presented with the Omni-Directional movement tutorial. Just complete this, it will be quite difficult to miss the prompt.

Kill an enemy from behind while disguised by the Sleeper Agent
Sleeper Agent is a field upgrade you can get after reaching level 51 in Multiplayer. Equip the field upgrade and enter a match. You can either shoot or take down from behind and the achievement should pop.

Destroy 50 Aerial Scorestreaks with Launchers in Multiplayer
Once again, if any other CoD's are to be drawn upon, destroying aerial scorestreaks will be part of the camo grind for Launchers. Otherwise, just bring a Launcher as a secondary and just blasting away every time some guy brings in a UAV or C-UAV. Poor guy.

Get 75 Eliminations while having an active Combat Speciality Perk in Multiplayer
Active Combat Speciality Perks are the 'skill tree' aspect of perks. Equip all perks of the same colour and you will get the 'Special Perk'; Enforcer, Recon or Strategist. Now just kill 75 enemies.

Enter Prestige 1
This will come with time, or if you want to get it quickly, I'm sure there are/will be certain XP farms or grinding tips, tricks and methods. I'll list some of the tried and true methods from older CoD's below;

Double XP Tokens and Weekend - Undoubtedly the most important factor in the XP grind. I had to add this as it is the way the majority of people go for max player and weapon levels.

Domination - Easy to pick up, kills come quick and the mode lasts quite a while. Focus on the objective and defending the objective for the most medals/score to make the most XP. Of course, you probably already know this.

Complete Challenges - As we are all aware, challenges provide extra bonuses to the experience and help the grind out immensely. If you want to level up quick, focus on trying out new weapons, levelling them up and completing camos, playstyles and experiences within the game. Find the challenges that suit you.

Team Deathmatch - Rather slower of a method however, as games slowly fade, TDM tends to be the most (only) played mode after the heyday of this year CoD's.

However, most notably, play the mode that you enjoy the most. There is no reason to play a mode that you do not like and burn yourself out. Focus on whatever you want to play and just have fun with the game because after all, it is a game.

Earn a Mastery Badge for any weapon
Fairly simple, follow the requirements for a weapon and you'll get it eventually. It will also most likely come with time as you progress with your favourite weapon. The requirement is usually getting kills. Although if you are unsure, head to your Barracks, Challenges then into Mastery Badges.

Unlock any Diamond or Opal Camo
If past Call of Duty's are anything to take experience from, the Camos are achieved through certain challenges and prerequisites to unlock further camos. As with the previous achievements, you can do this in either Multiplayer or Zombies. Pick any class of weapon (Assault Rifles, Shotguns, Specials, etc...) and get Gold/Mystic Gold camo on every one of the weapons in that class.

For those curious, the camo route goes as follows;
Multiplayer = Gold > Diamond > Dark Spine > Dark Matter
Zombies = Mystic Gold > Opal > Afterlife > Nebula

Get out of jail, but not for free
This is the Terminus Easter Egg, below is my full and detailed guide for all Easter Eggs.

https://cs2bus.com/sharedfiles/filedetails/?id=3315583416

In Terminus, consume a fish cooked with a special ingredient
After activating Power, you will have unlocked all areas needed to start this achievement. This achievement requires you to find several items, interacting with them, and incorporate them into a frying pan with a fish. The following list shows where to find all the ingredients;

• First Unicorn Plush, found to the left of Stamin-Up in a locker.
  
• Battery, found on a bench in the Engineering room.
  
• Second Unicorn Plush, in the Jugger-nog room, to the right of the generator on a bunk bed.
  
• Butter, on top of a fridge opposite the pool table in the same generator room, upstairs.
  
• Can, found in the Mess Hall in the East corner besides some vegetable boxes.
  
• Cooking Oil, found in the Mess Hall in the South-East corner of the room on a metal shelf, next to the frying pan.
  
• Brain, found in the PaP room, directly opposite the door you enter in when coming from Speed Cola caves.
  
• Fish, found in the PaP room, in the water, find a fish and just blow it up then interact with it.
  
• Finally, add all the aforementioned ingredients to the frying pan in the Mess Hall. Simply end the round you are currently on to allow the ingredients to cook, and interact for a final time.

In Terminus, find the final Talisman
Before starting, select the Molotovs lethal equipment as your Loadout, it will make this achievement a little easier. Also note that a Thermal Grenade works too, just need to get a little creative with the placement.

First of all, of course, turn on the power by activating all the generators. Then head down to PaP and buy Melee Macchiato. Once acquired, go to the Sea Caves where Speed Cola is located and opposite Speed is a stalagmite wall that you need to punch open with Melee Macchiato.











Take a look at the map that's shown and boat/swim over to where the red 'X' is on the map, here is where you will find a Wristwatch, pick it up and go back to the Sea Caves captain.











Now the Captain will point you towards 3 more red 'X's on the map, this time you need to light the bones that you find on fire and defeat several H.V.Ts, one per set of bones. The bones locations are always the same, so no need to worry about checking back with the map. Use a Molotov on the bones and take out the H.V.T, then pick up the item that is dropped by them. These can be done in any order.

• The first is located on the Shipwreck, by the Mast pole.

• The second is located on Temple Island, in a dip of the rock formation facing West.

• The third is located on Castle Rock Island, just opposite the Gobblegum machine on the other side of the rock formation. Be wary it's rather hard to see.

Once completed (with the 3 coins), head back to the Sea Caves Captain and give him the coins. Now you will need to survive on Crab Island for 3 rounds, so head there when you've gotten a decent loadout and just survive until a Chest spawns on the back of the island.

The lightning in the area is affected by the progress you have made, the more lightning, the closer you are to getting the Cursed Talisman. Once you've survived, head to the chest and open it for the achievement.

Help the lost scientist complete the experiment
This is the Liberty Falls Easter Egg, below is my full and detailed guide for all Easter Eggs.
https://cs2bus.com/sharedfiles/filedetails/?id=3315583416

In Liberty Falls, tap into your Supervillain side
Firstly, you'll need to build the Jet Gun, or rather the wonder weapon for this map. It is fairly simple, and thus I won't go into too much detail for it. The pieces are found in;

• Water Pressure Gauge - Found by taking the valve from the water pipe next to the flower shop beside Speed Cola and placing that into the Bowling Alley fire suppression system. Here you'll have to crank it for about 30 seconds while zombies run at you. Progress saves when you let go, so you can freely kill the zombies in between interactions.
  
• Handbrake - Found by killing a certain groundskeeper in the Graveyard next to the Church to get a key. Kill zombies in this area and he will eventually spawn in, kill him and take his key. Then go to the Shed next to the crafting bench nearby and open it to find the part.
  
• Electrical Wires - Found in the Electronics Store just outside of spawn, opposite the bank. Build a Mangler Cannon, or have a Mangler shoot at, the shutter gate in the shop. Then waddle in and start digging up piles around the area. It will be in one of those piles.

Then go to a room upstairs in the Motel in Spawn and build the Jet Gun in the room all the zombies run out of.

Now what you need to do is find Nine figurines around the map. I'll try make the route as least tedious as I can. Follow the screenshots and order below.

Bowling Alley >> Church >> Speed Cola Roof >> Bank Roof >> Spawn >> Arcade

In Liberty Falls, achieve a sporting high score
This isn't as daunting as it sounds, the 300 score isn't so bad to get and results in a Dark Ops calling card alongside the achievement, so win win. Just takes a little bit of practise. Aim for crowds of zombies and charge your ball to hit multiple.

All you need to do is find and shoot 5 pairs of shoes around the map. You will then be teleported to the Bowling Alley and be let loose to kill the zombies. The shoes are in the following locations;

• In the refuelling station in Spawn, look inside the barrier window to find them on the cashier desk.
  
• In Frank's Hardware, left of the Electrical Store, on a market shelf on the right hand side of the barrier
  
• Inside a house on the hill leading up to the Church, right hand side with the stairs leading to the front door, they'll be under a chair on the right side of the barrier.
  
• At the far end of the Graveyard beside the Tier 3 armour hanging off a tree.
  
• In the Benson Burial Services building opposite the Bowling Alley, far left of the barrier on a coffin under a painting.

Here are the screenshots in the order left to right following the previous list;

Get 100 Kills while using Mutant Injections in Zombies
The Mutant Injection is an item that can be crafted using Salvage or occasionally dropped by Special and Elite enemies. Using any attack that the Mangler has against the zombies seem to count towards this.

Research all Augments for 10 items in Zombies
Augments are these cool little mini-abilities that each Perk, Alternate Ammo Type and Field Upgrades, all you need to do is to start researching an augment for any of the aforementioned.

Thankfully, augment research continues progressing after finishing, so you can do this in one game, provided to live long enough.

Get 100 Elite Zombie Elimations in Zombies
Elite enemies are Abominations and Amalgams. You will get this in time, but Rounds 15-16 are when they make their first appearances.

I have made guides for other Call of Duty games, should you require them :)
