How to unlock the Ultimate Armament achievement in CODE VEIN - Definitive Guide
Level 1 - Level 2 = 1 Queen Iron
Level 2 - Level 3 = 2 Queen Iron
Level 3 - Level 4 = 2 Queen Steel
Level 4 - Level 5 = 3 Queen Steel
Level 5 - Level 6 = 5 Queen Steel
Level 6 - Level 7 = 2 Queen Titanium
Level 7 - Level 8 = 3 Queen Titanium
Level 8 - Level 9 = 5 Queen Titanium
Level 9 - Level 10 = 2 Queen Tungsten
You will be able to find Queen Iron and Queen Steel from Ruined City Underground to Cathedral of the Scared Blood are most common.
The queen Titanium from Cathedral of the Scared to the Crypt Spire are most common.
And the Queen Tungsten is only found on Provisional Government Outskirts and Provisional Government Center. The main enemy that drops this will be some of the Queens Elites. They are the ones that are white, plus they are also females. Once you hit the final upgrade the achievement will pop.
In similar vein to Dark Souls, a weapon can be upgraded to +10 with upgrades of increasing quality. In order to do so, you need a grand total of 7 Queen's Iron, 10 Queen's Steel, 10 Queen's Platinum, and 2 Queen's Tungsten. Coco will start selling Iron, Steel and Platinum eventually but Tungsten can be found when you reach the Provisional Government Outskirts. Tungsten is also farmable in both the Provisional Government Center and Zero District depth maps so do not worry about missing this achievement. Upgrades are done via Murasame the weapon vendor and I recommend keeping your favorite weapon and blood veil upgraded often to make the game easier on yourself.
