You get this Achievement too

This is not a solution, but a warning:

THE ACHIEVEMENT CAN GET GLITCHED and i know why and how to solve the problem.

The first thing I want to suggest is that you should collect all the upgrades as you progress through the campaign and be careful if you do the collectibles upgrades after you've beted the campaign.

So... I beat the campaign on Veteran and I did not take care of the upgrades, as i wanted to collect them after. I had follow the Maka's guide above, which is actually a very good guide (can not complain).
The problem that has arisen is partly my mistake and partly a bug in the game. -If you ask me, I can not agree with a 2016 game that does not save all 2 upgrades when you press "X" to collect a station and i can not agree with the game to not display your missing collections in the "Mission replay" list. OK... So in my game I collected 2 of the 8 upgrade stations and then resumed the missions to collect the rest.

There are some upgrade stations that offer you // 2 // upgrades(see the Black Flag upgrade station), and the rest will give you 1 upgrade. When a station offers you 2 upgrades, the stupid game system will display 2 pop-up windows for the upgrades that youll get >> one after the other << in the top left corner.
When I resumed the Black Flag mission, the upgrade station would have to give me two upgrades instantly (ATAD v1 and Foam Wall v1), ie two pop-up windows, one for ATAD and one for the Foam Wall. The game gives you a save for the ATAD and another save for the Foam Wall, as soon as the pop-up appear. There is the problem: If you quit the game believing that you get all the collectibles when the first pop-up window appears, you will only get the ATAD upgrade(1st) and not the Foam Wall upgrade too(wich is the 2nd.

Also, this is what i do(mission Black Flag): I quit to menus(as the Maka's guide says) and i didn't wait for the second upgrade window pop-up, because i was in hurry for the achievement, and the game has saved only the ATAD upgrade but not the Foam Wall too, because i didnt get the left top window, because i quit imediatly after pressing "X".

SOLUTION:
You can not get the second upgrade from the Black Flag station anymore(Foam Wall v1) if you do the quit like i do. (Stupid game system).
The only solution to get all the upgrades after this mistake is to delete your HDD and Cloud save file from the "Manage game" and then start a brand new game, but this time wait for all station upgrades pop-up windows, and you will be well. --For your safe go forward to the next cheekpoint for a complete save.
--If you start a new game on the Recruit and you will skip the cutscenes and make a quick run, you will reach your last mission with an upgrade station (Black Flag) in about 3 hours.

I've seen so many people complaining about this mistake and error and nobody got an answer. (Maybe they do the same: They quit the game at the first pop-up window in Black Flag mission.) I've been looking for for 2 hours on internet and nothing.

I hope someone will find the reason and the solution for this problem here. Also, I don't care of the negative votes that i will probably will get because it is just a warning. Hope you all do not get glitched and thank you!
