    I am currently working on this achievement so decided to put together a spreadsheet for people (and myself) to use in order to keep track of progress towards all the Survival Armories Achievements. As far as I can see the game only notifies you of weapons and items which have been unlocked for purchase, not what you HAVE purchased which is annoying.

    I have uploaded this to google docs and is accessible from

    I have set it for public viewing and usage so you should be able to make a copy and print etc.

    I have included next to the items the level which is required to unlock them for purchase and what it will cost you. These items can be unlocked in multiple playthrough's so keep at it and you will get this.

    Any problems with the link or any improvements you think could be made let me know.

    Hopefully this is of use to everyone. Thanks for looking. RB

    The achievement requires you to purchase each of the items in the armory atleast once. The armory is marked by a Grenade symbol on the map and on your screen. You do not have to buy everything in one match this my be completed in mutiple matches.

    For this achievement you are required to be the rank of 37 in spec ops this takes 939,600 xp. This is due to the fact the riot shield doesnt unlock till 37. Spec ops ranking system is seperate from Multiplayer so any rank in mutiplayer wont be required.

    What you have to buy-
    ARMORY- Equipment
    Name- Cost-
    Grenade 750
    flashbang 1000
    claymore 1000
    C4 1500
    Rpg 2000
    Body armor 2000
    Self Revive 4000
    Sentry Gun 3000
    Sentry Grenade launcher 4000
    Riot shield 3000

    Total- 22,250 points.

    Things you should know you can not have two sentry guns or one sentry gun and one sentry lancher at the same time you must place one on the ground before being able to buy another. The self revive may also require you to buy another perk or get downed atleast once before buying it this is due to starting the game with it when you unlock it. If it does this can be done easyly with one enemy left in the wave or buy another perk from the air support armory marked by a airplane on your screen.

    Easy ways to rank up -

    Missions - You can play each mission in spec ops on veteran by yourself and gain upwards of 33,000 points a mission completed for the first time.

    Survival - Doing the first survival map by yourself can get you quite a bit of xp from kills but may take a while.

    Grinding - Have found a method that can get you anywhere from 4000 to 8000 points in just one minute.Set difficulty to veteran(or can put it on any difficulty you prefer), on the first part of server crash you start in a car. You can run through this sequence and destroy each car netting you 700 or more points per a car destroyed. Will try to make a video if call of duty elite allows it , of a speed run through this method and where to shoot to maximize your point gain. Here's a video showing the mission in the mean time.

    Easy ways to gain cash in survival -

    Please look at my solo method for the Get rich or die achievement (get 50,000 points in one match) to help you get money faster to buy each item.

    Please thumbs up if this helps and if theres anything wrong comment and ill try to fix it Thank you!

    CraftyZach manoh you probably did what most did if you start with a certain gun or perk already equipped it doesn't count for having them you have to lose them then buy them again for it to count.

    For this achievement, like it says, you need to buy all the items within this Armory (the one that has the Grenade symbol above it). Now what I found out, is that you don't need to buy them all in one match, which is what I thought initially, but all it requires is that you buy them all throughout multiple playthroughs. Meaning, it's cumulative from every Survival map you play. Also I should note, that you need to level up within the Spec Ops, which is separate from the online rank of course. When you get to certain Levels you will unlock the items.

    Vestri Sator^^Not for this achievement, but it does include them for the weapon one. Keep in mind that there is 3 variations for the grenade launcher attachment and you have to get all three of them.

    ColtoN899For the item that requires the highest level you need to be level 50. (37 for this one achievement, but 50 for the other achievements).
