Comment #4 by XBOX ISAAC82
Thursday, November 10, 2011 @ 10:45:30 AM

Yeah, but I am assuming it is only one set of attachments, do not have to purchase each set for each weapon. If you go into Barracks and select 'Survival Armories' then weapons you'll see Weapon Upgrades rather then a set for each weapon.

sorry for my approximate english

can you tell my on whitch weapon we can equip the accessory launch grenade M203 because i didn't find it

thank you in advence

Comment #6 by EL1T3 x
Thursday, November 10, 2011 @ 05:14:45 PM

So just to clarify... We don't have to buy each attachment for each weapon? So say if i was to buy 'Grip' That would count throughout all weapons that have 'grip' available?

Comment #7 by M a r k Xlll
Friday, November 11, 2011 @ 07:33:16 AM

No, if you buy 'Grip', only the gun you bought it for would have it.
I think they actually want you to buy every gun, and every attachment.
In other words, good luck. Also, it never says in one game. So I think
it means to buy every weapon and attachment over time.

Comment #8 by Evan of Aus
Friday, November 11, 2011 @ 10:01:37 AM

Would like to find out if this is cumulative or in one game. hoping for cumulative

Comment #9 by DJLimeRecharge
Friday, November 11, 2011 @ 10:14:00 AM

It IS cumulative. I got the equipment one by buying a riot shield, but I hadn't bought the RPG in that same game, but have in a previous game.

Comment #10 by totemman16
Friday, November 11, 2011 @ 12:01:37 PM

all attachments for all guns.

Comment #11 by Rampagin Sheep
Saturday, November 12, 2011 @ 04:09:19 AM

To clear everything up for everyone: Every gun has to be purchased
from the store, this includes guns you've picked up and/or started
with. As for the attachments, they must be purchased once and only
once. There are just a few different guns required to get each under
sling. So to be clear, if you buy the grip for any gun, it now counts
as being purchased and you don't need to buy it on any other gun, same
goes for the sights, etc.

Hope this helps clarify for anyone who was confused, I know I was until
I got this.

(And don't forget to buy the ones you get early on, the damn
MP5 was what I forgot and I wasted a few hours trying to figure out
what I had missed).

Comment #12 by Rampagin Sheep
Saturday, November 12, 2011 @ 04:10:42 AM

Oh and #9 is also correct, this can be done over as many games as
you please.

Comment #13 by DanielRoyLivall
Saturday, November 12, 2011 @ 04:11:50 AM

I'm pretty sure you only need to buy each attatchment once, for any gun.
For the grenade launchers, the M16, M4A1 and the SCAR all use a differe
nt one. :)

Thanks buddy that helped alot

Comment #15 by BRAVO COMPANY69
Saturday, November 12, 2011 @ 01:25:58 PM

@Rampagin Sheep, so say if i get all the attachments for my M16, i DONT have to buy that attachment for any other gun, so i can just get like one gun with all the attachments then get the guns and any other attachments i didnt get?

Comment #16 by Daniel55645
Saturday, November 12, 2011 @ 01:49:47 PM

thank god this doesnt have to be in one game. just made this game from a very hard 1000 to a fairly easy 1000 just cause of this ach.

Comment #17 by PhR33kN SlAcK3r

Saturday, November 12, 2011 @ 03:22:03 PM

Just got this along with unstoppable, survivor and danger zone and my 1000/1000..

You need to buy every weapon and attachment once, it's also cumulative. Just be sure that you buy starter-weapons (like the five-seven) too.

Comment #19 by Rampagin Sheep
Saturday, November 12, 2011 @ 11:34:54 PM

#14, that's exactly what I posted because I was annoyed I couldn't get
a straight answer anywhere.

#15, yes that is correct.

Ok just so everyone knows did this several times solo and never unlocked YOU HAVE TO BE ON MULTIPLAYER for it to unlock DONT DO IT SOLO Total waste of time. IT WONT UNLOCK

Comment #21 by DivineWarlord

#20 You're wrong. I did this solo just now.

Comment #22 by CombatVet IZ AF
Sunday, November 13, 2011 @ 11:56:14 AM

A good way to keep track is to focus one weapons set per game. Do all the handguns, then the machine pistols, then the assault rifles, etc. I waited until I had enough $$$ and bought them all at once - including the starter/pick-up weapons. This way I could track my own progress.

Comment #23 by FiReStOrM^
Sunday, November 13, 2011 @ 03:10:43 PM

I know I have bought everything but no ach. I saved enough to buy a whole set and save it it notepad (ex. Handguns, Machine Pistols etc).

My question is though I just bought one, then the next and so on. Do you have to buy one then exit and buy the next or has something just not registered for me, as i know i have bought everything.. including attachments.

Comment #24 by nuer
Sunday, November 13, 2011 @ 04:01:01 PM

do you actually have to buy every attachment for every single gun?

Comment #25 by FiReStOrM^
Sunday, November 13, 2011 @ 04:43:02 PM

No you just have to buy them once.

According to the guide, this is all you need:

Attachments (Can be purchased for any gun)

* Red Dot Sight (cost: $750, unlocked at level 7)
* Holographic Sight (cost: $1000)
* ACOG Scope (unlocked at level 3)
* Shotgun Attachment (unlocked at level 45)

I have bought ALL attachments though in my quest to get the ach (was missing a silly SMG somehow) so I can't say whether or not you actually need the Grip and the grenade launcher, though might as well just get them too.

Monday, November 14, 2011 @ 02:06:07 AM

Hey this may help ur question. Enable ti get thus you have to reach level 50 pretty much it cause i'll be done. N yes u have to buy all weapons n attachements too.. the total to gets all weapons is $111,500 dollars plus the attachments total of $12,500 which adds $124,000 if you could reach that amount. Hope this helps. Also if you like to do this My GamerTag is WannaBeMasterJr

Comment #30 by VictorX23
Monday, November 14, 2011 @ 05:49:49 AM

You have to buy every attachment once. NOT for each individual gun. You also have to buy every gun, including the hand gun you start off with. so anyone who has gone through every gun and attachment, buy a weapon (to use up your second) exit switch to your original handgun, buy something different, then buy the five-7 back. should help you get the achievement.

Also #20, you can do it solo and through multiplayer. I've done it and so have others. It's stacks up through out all playthroughs so you don't have to get it in one sitting.

Comment #31 by VictorX23

wtf?! i have bought every weapon and every attachment, yes even the starting pistol, multiple times over now and no achievement. i have done it solo AND multiplayer. and it seems like im the only damn person with this problem? did i magically get the only glitched version of this game on the planet? and of course its the last achievement i need for the stupid game. if anyone has ANY idea how to help, it would be greatly appreciated. gamertag is ThePaleHorseman if any are so kind to help.

Comment #37 by Miss Jokerr
Tuesday, November 15, 2011 @ 09:22:58 PM

just buy all wepons, handguns, machinepistols, shotguns, sub machine guns, light machine guns, snipers, assaultguns
play private survival 2players

1player makes money
2player, cover and buy the guns

you can sent money over bye the box where u buy your guns, pres "X" and u sent 500,- to your teammate
play a easy map, you also need a good teammate;)

Comment #38 by I Ri0t Kyle I
Wednesday, November 16, 2011 @ 12:04:17 PM

so im having the same problem as @34 & @35 i know i have bought everything but it hasnt clicked on yet so i wonder if some of you are wrong.

someone said that you must buy everything ONCE that is a little far fetched surely you can buy something more then once? because i have bought things countless amounts of times?

also i think that if i bought i dunno grip for the l86 (lmg) that would register that every gun that i have with the avalible grip attachment has been unlocked, if you bought grip for an lmg it may be unlocked for the rest of the lmgs but not the shotguns?

i am also someone who has spammed the store buying the weapons but not actully using them for those who are having trouble with this acheivment should we get a kill with the weapon before buying a new one?

Comment #39 by wirelesszebra
Wednesday, November 16, 2011 @ 02:44:33 PM

im just trying to help people here and i have not got the achievement myself but for those who say that it has glitched for them have they tried refilling the ammo

Comment #40 by cam91191
Wednesday, November 16, 2011 @ 03:04:22 PM

Just got this achievement. You only need to buy each attachment once, not the same attachment for every gun that can equip it :) and just remember to buy all the guns, make a list of what you've done so far, final guns unlock at level 50.

Comment #41 by TheJvv15
Wednesday, November 16, 2011 @ 05:11:18 PM

this was crazy because i bought every gun and attachment but i don't get the achievement and i was like WTH? then I did it again and nothing happens i thought it glitched on me but it turns out that i forgot to buy the 1st gun it gives the Five Seven I just blown my mind away. That was an Epic Fail, so this is my advice buy the Five Seven before you go crazy

Comment #42 by Aguero
Thursday, November 17, 2011 @ 03:52:43 PM

Remember to buy M4 + granade launcher, Scar-L + granade launcher, AK-47 + granade launcher. Those weapons have different granade launchers so you must buy them separately.

Comment #43 by iHazard xD
Friday, November 18, 2011 @ 06:54:33 AM

I think its best to buy all Handguns first, then go down the list, just makes it easy to keep track of what you`ve bought.

Comment #44 by ltskitzo
Friday, November 18, 2011 @ 07:21:40 AM

Making your way through the list, in a progressive order is the best idea, because other wise you can easily lose track. Although it has already been stated I will remind that only one of each of the attachments needs to be brought.
In all honesty though, getting the guns wasn't the problem, getting to 50 was. and I found grinding the last level of spec ops is the quickest way to attain this. plug in a second controller, be the AC130 and pummel the enemies that come, you'll get 2350+ points every 15 seconds if you reset the level every time the helicopter dies and all the other immediate enemies are dead.

Comment #47 by gravelandx88
Friday, November 18, 2011 @ 02:00:10 PM

I just unlocked the achievement a few mins ago. Should of read the guide first as I bought every weapon w/o the attachments. Realizing my achievement didn't unlock. I started with assault class. Bought all the attachments for 3 weapons & got it finally unlocked.

Comment #48 by gravelandx88
Friday, November 18, 2011 @ 02:03:29 PM

(cont) just bought the 3 different grenade launchers for the 3 different assault weapons. Nothing else. Hope this helps, if anyone is stuck.

Comment #49 by gravelandx88
Friday, November 18, 2011 @ 02:11:11 PM

@45, its not that hard. Start from the top and work your way down. Like someone written above, make a checklist. If you have a hard time keeping track. Should take no more then a few games to unlock it. I recommend playing on Resistance.

Comment #50 by Koochi
Friday, November 18, 2011 @ 04:56:18 PM

The gp25 is the grenade launcher 4 the ak47
The m203 is for the m4a1
The m320 is for the scar :D

Hope this helped :D

Comment #51 by ThePaleHorseman
Friday, November 18, 2011 @ 06:02:44 PM

ALRIGHT. got it finally. to those of you who have the problem of it not unlocking, dont listen to all these people who say "oh you missed the first pistol". what i did to get it was clear the cache on my hard drive. when i started up the next game, as soon as i got to the lmgs it unlocked. so try that, hope it helps.

Comment #52 by Mr Ice Tea
Friday, November 18, 2011 @ 09:30:31 PM

k so do you have to buy the weapons or can you just pick up the weapons as you kill the
enemies im very confused if someone could please clarify for me :)

Comment #53 by XxBlazeEmblemxX
Friday, November 18, 2011 @ 10:02:45 PM

You only have to buy each weapon once, each attachment for whatever weapon once. Lvl 49 I believe, is when you unlock the last weapon so basically just lvl up to 50 and play a few games to unlock this achievement.

Comment #54 by Deniablefrog
Saturday, November 19, 2011 @ 11:52:57 AM

Monday, November 21, 2011 @ 02:53:40 AM

I saw that first you need to be a high level like 44 to be able to buy for example .44 Magnum is that right?
If so, there is a loong time to play...
Please confirm.

Comment #71 by Agent Carrot
Tuesday, November 29, 2011 @ 01:51:49 PM

Just buy your weapon, for example the AK-47, and once you've bought it, it says upgrade. Just click on upgrade and you'll be able to buy your attachments.

Comment #72 by locoloco
Wednesday, November 30, 2011 @ 03:31:54 PM

I just got the achievement, there isn't a problem with the chievo, it's user
error. This can be done in solo; Here's what you need to do:

Make a full weaponry list for guns and attachments. Once you buy the gun and/
or attachment, mark it off the list immediately.

Here's a list of commonly missed guns that you MUST buy:
Model 1887
Five Seven
ACR 6.8

Don't forget you only need to purchase an attachment once in order to check
it off your list.

Pretty simple. Just had one gun left and had no idea what it was. the darn PM9

Comment #83 by DrGreenThumb305
Saturday, December 10, 2011 @ 04:46:41 PM

It's VERY easy to lose track of which gun is needed in the end. I needed to buy the model 1887(first shotgun you pick up!)

I started going for this cheevo when I got the 50K achievement. I went down the list starting from the handguns and got up to the second LMG, but I wasn't a level 50 so I figured I'd try again when I got to 50. Anyway, once I got to 50.. it took me about 5 games because I just couldn't figure out what was missing and/or which gun required which attachment.

Here's a few tips to make sure you don't mess up.
1. Don't bother trying this until you get to level 50
2. Do it on easy(obvious, I know)
3. After the 3rd wave, head for the weapons.
4. You should have a shotgun and a handgun at this point. First, equip your handgun and access the armory. Select the second

Comment #84 by DrGreenThumb305
Saturday, December 10, 2011 @ 04:50:22 PM


select the second handgun(usp) and purchase it. Then, back out of the inventory and switch over to your shotgun. Now access the inventory again and purchase your first pistol back. From this point on, just work your way down the list until you are out of money.

5. Leave AR's for last because you have to buy attachments for some. You might as well buy them when you are ready to purchase the attachments as well.

6. Making a list of what you have purchased would not hurt. Remember that weapons you pick up off the ground also need to be purchased.(in my case, the model 1887)

Good luck!

Same Prob here.
Buyed everything and still no chieve..
Very bad of A;vision, they had to make something that can keep track of the guns/ atachs you've bought in survival, that would make ik more easy to c what you've missed (in case you did) or not.!!!

This game needs an update!

Hey I just got this achievement finally. Had a checklist of all weapons and sort of spammed the armory to go through the list. Didn't need to get a kill or even use the guns. The only tricky part was to make sure to buy the grip for any LMG and also buy the 3 different grenade launchers (the M4A1, the SCAR, and the AK-47). After I did that it unlocked. Woohoo :D

This is so easy, why do people get worked up!
You have to be rank 50 to do it mind.
You do not need to use the items, ie buy the care package crates for the perks and just launch the flare, that is enough. You don't need to collect the crate.
And I would reccommend keeping a basic tick list for the guns. Very upsetting when you miss one and can't work out which one!

finally got this!

easiest way wait till your level 50. you can get it either solo or multiplayer btw
as i did both and got it.

i used this link
TICK off each gun as soon as u buy it makes this SO much easier!
turned out i missed a sniper!

What many of you are probably forgetting for this achievement is to go back and buy not only your starting weapon, but also go back and buy the weapons that the starting enemies dropped. I finally got this achievement after carefully going back through every list just to realize that I missed the Model 1887 shotgun.

Some common ones I found to miss were the:
Five seven
Model 1887
and the MP5

Hope this helps

I'm certain i've used every gun in the armory, but yet i still get no achievement. do i have to use an attachment with each gun. or jsut buy the gun and use it. i'm on my second run through with buying all the guns. usually takes about 2 or 3 games to do it. i dont want to waste my time any longer on this achievement. can someone please advise to what i should try. and yes people. i have bought the guns you start the game with.

I want to make this easier for you guys. I've just gotten every achievement last night, this being my final achievement. YOU DO NOT HAVE TO DO THIS ALL IN ONE GAME!!! First of all, buy every weapon. Secondly, buy attachments. Now, when you buy a Holographic Sight, you only have to buy it for ONE weapon. It doesn't matter which one. Then, you never have to buy it again. The same goes with the Red Dot Sight, Acog Sight, Grip, and Shotgun attachment. These attachments are the same for every weapon. And when I mean ONE weapon, I don't mean one in every weapon type. I mean ONE WEAPON (preferably the M4A1). However, there are different Grenade Launchers. Buy one for the M4A1, one for the SCAR-L, and one for the AK-47. You also have to Refill your ammo. That's it. But remember, when you buy a Hol

But remember, when you buy a Holographic Sight/Red Dot Sight/Acog Sight/Grip/Shotgun attachment for the M4A1, it counts towards Machine Pistols, Shotguns, Light Machine Guns, etc. And you do not have to do everything in one game.

Friday, December 30, 2011 @ 05:07:24 PM

I was just about to come on here and rant about how the game is glitched and I got it while the laptop was starting up ! The advice I'll give people is to go through the lists one by one and buy as many attachments as possible in each visit to the computer. I bought both granade launcher and shotgun attchments then went back next turn and bought all 3 scopes. I had to do it 3 times because I missed something each time, but with a bit of planing and a bit of patience it can be done.

Comment #97 by DragonBane
Monday, January 02, 2012 @ 12:25:18 AM

I have just discovered something no one else has mentioned in any of the previous posts. The purchase of any weapon or attachment is cumulative, however it appears that the game does not cross reference purchases made on different maps. [I do not have an updated game, so this could be fixed now] I discovered this when I frustratingly made a checklist of every weapon and attachment and went through everything without unlocking Arms Dealer. I started off on Bootleg, and I only purchased shotguns up to the Striker on it and decided it would be easier to do this on Underground. I didn't unlock the achievement until i finally repurchased all the shotguns through the Striker on Underground where I had purchaseed everything else. Hope this helps!

Tuesday, January 03, 2012 @ 09:05:01 AM

i am currently working on this. I plan on finishing it tonight. anyway, it seems if you are at level 50, it might be a good idea to start your purchases at the BOTTOM of each weapon category and work your way up. the enemies do not drop weapons at the bottom of the list, and if you start there and go up, you will buy things you have already picked up from the ground and you will purchase any weapon you may have already started with.

Comment #99 by jguzman8618
Tuesday, January 03, 2012 @ 02:35:05 PM

You have to BUY every weapon, that means you have to buy the pistol you start out with and you have to buy the guns you pick up too, and YOU ONLY HAVE TO BUY EACH ATTACHMENT ONCE, NOT ONCE FOR EVERY WEAPON, JUST ONCE. Just keep track of the stuff you buy.......

You have to buy all the weapons on the same map. I was having trouble because I wasn't getting the achievement and I knew I had already bought all the weapons and attachments. Then I tried buying them all on the same map and it worked. You only need to buy the attachments once. Just got it.

So you only need to buy all the attachments once? I go through each weapon and buy the attachments for that gun. then go on to the next one.

Sunday, January 08, 2012 @ 02:43:53 AM

Some of you asked the question of, "Do I have to get a kill with the weapon and weapon and with so and so atttachment." Here's my answer, and what I did:

I Went through and bought every gun. I did this buy buying the all of the Pistols, then buying all of the guns in the next 'set' of guns and just kept going down the list and bought each gun in each catagory. I bought them all by rapidly pressing A on them, so no, you don't have to get a kill with each weapon and with each weapon attachment, and you don't have to back out of the purchasing menu. Just buy them all. But like others have said, make sure to do this all on 1 map. I did it on Dome because it is the smallest and you can make it up to Wave 10 rather quickly, then spend all of your moeny on the things you need, and then let th

I could not for the life of me get this to update. I played in multi-player and it finally updated when I bought the first sniper rifle. I think there may be some glitch to where you have to buy at least one gun from each category while playing with someone else on-line for it to update for some of us.

Hey, I just wanted to let everyone know that the two guns that seemed to have slipped by me were the G36C and the USAS12. Also, I counted the kills I got with each weapon, and I got a minimum of 10 kills with each gun. That may help, but I'm not sure.

I would also like to thank everyone that tried to help out with getting this achievement. I got through about 50 posts, so I just wanted to say thank you to all of you. Gamertag is NightSpyd3r if anyone ever wants to play a game, or needs a partner to send money in a survival mode. I average out about 5 grand per level because I usually get high kill chains. Just a heads up to anyone interested.

Thanks again.

Adding my tips.

Buy each weapon once.
Buy each attachment once.

You DO NOT have to buy each attachment for every gun.
You DO NOT have to kill people with the gun simply buy it.

I know you don't have to buy the attachments for every gun. As I never
did and it gave me the achievement after I bought the grip for
a shot gun. I also did not kill at least one person with all guns.

If you know you won't do it in one sitting try to create a list of some
sort. Write down all the guns in the category and check them off.
So when you come back you know where to carry on from. As to avoid
missing guns and having to start again.

Comment #114 by Brethren
Wednesday, January 18, 2012 @ 09:18:31 PM

Is it possible that the people who are unable to get this to unlock, are simply exiting the game after acquiring the guns? For other survival progress, you need to end the match by dying, other progress is lost if you exit early. Just a suggestion. Personally, I am still trying it myself, so Ill make another run for it on solo survival on an Alpha mission.

Finally got this last night. Thought I had everything, reached Level 50, bought Slight of Hand and the Barrett...nothing. Read through here and decided to try buying the "common" weapons before starting all over (Five Seven, Model 1887, and MP5)...cheev popped when I bought the shotgun :)

My advice if you think you've bought everything is to try buying those three guns first, then be sure you buy the correct Assault Rifles for the three gun-specific grenade launchers (M4A1, the SCAR, and the AK-47). I think the one for the SCAR works with all other rifles as well.

Good luck!

Sunday, January 22, 2012 @ 05:10:34 PM

It was the MP5 that got me - had bought several groups of weapons (handguns, shotguns, small machine guns) twice over before I wondered whether I had actually *bought* the MP5.

I agree with several of the others though: wait until you hit Level 50, play Resistance and amass a huge amount of money, and systematically buy all the weapons group by group. Make a record of your purchases if you feel unsure. It should unlock easily. And note the grenade launchers.

Sunday, January 22, 2012 @ 09:38:50 PM

Comment Number 97 is perfectly right..I bought all the LMG's and SMG's while playing village and assumed when I was plying Resistance I didn't need to buy them
I bought everything Ecept these while playing Resistance and no Cheevo Popped so I tried what 97 said and boom Cheevo Popped

You have to get all these guns on the same map over time

Have seen a couple of posts stating that you have to buy them all on the same map over a period of time, not true. Everytime i ranked up i bought the new weapon there and then, so have bought the weapons over nearly every map. Unlocked the achivement last night with no dramas.

Comment #124 by DirizRollsDice
Thursday, February 16, 2012 @ 05:46:05 PM

My summary:

Buy every single item ONCE, including attachments.
You don't need to get any kills with your weapons, just buy them. Buy them all.
Tip: Save up $20,000+ using your favorite guns (my best setup is ACR + MP7), then go on a shopping spree. You might want to save a bit of money left over so you can buy your favorite guns back.
Don't forget to buy your starter pistol. This was the USP .45 for me.

You people saying the game is glitched and you've done everything 3 or 4 times are missing something. Period. The game is not glitched. It's extremely easy to lose track of what you've bought. It does not have to be a single game; it's cumulative. Not sure if you quit early it erases it or if you have to finish the level by death (I always do just to be safe).

Remember several assault rifles share the same grenade launcher. You may have purchased the same one not noticing it was the same because it was a different gun. I still need this achievement, but it's my own fault because I started before I was 50. I'm doing the checklist that has been provided now, but I'm guessing I'm missing a grenade launcher.

I also reccommend you all to do it on an easy map like underground because even wen with a friend it takes up until round 28 with me.. much easier on co.op because all the money ur friend earns.. he can send u or vise versa.

Monday, April 09, 2012 @ 11:05:28 AM

You only have to buy the attachments once, if the attachment is the same across multiple guns. This means that you can buy the Red Dot sight once, for one weapon, and then you won't have to buy it again on another gun.

The exception to this is the grenade launchers, which are different on 3 ARs:

AK47 (GP25 grenade launcher)
M4A1 (M203 grenade launcher)
SCAR (M320 grenade launcher)
You must buy all three of the grenade launchers for this.

You don't have to do this in a single survival match, it's cumulative. Keeping track of what you've bought can be tricky, however. You'll need to make it to level 50 before you'll unlock everything. Some suggestions I read include:

Buy a whole class of weapons out at once, so that you know you've gotten them all.
Get a whole bunch of money

Implicit in this achievement is the fact that you will have to play many many hours of Spec Ops in order to rank up and unlock all the items in the armories. Bear that in mind when you start checking off your list.
