Call of Duty Modern Warfare’s multiplayer and spec ops modes feature a large variety of weapons that can be unlocked by leveling up. Additional weapons have been added through free updates that can be unlocked by completing challenges.
Both multiplayer and spec ops share the same rank progression and unlocks. Create and sign into a Call of Duty or Activision account in the options menu to also enable cross-progression on PC, PlayStation 4, or Xbox One. Newer Call of Duty games will share the same rank progression as well, but with unlocks specific to that game.
Create a loadout for Multiplayer or Spec Ops using one primary weapon, one secondary weapon, one lethal, one tactical, and three perks. These loadouts can also be edited by bringing up the Pause Menu in-game. Primary and secondary weapons can hold up to five attachments each, which can be equipped using the new Gunsmith feature.
The Perks are separated into three different tiers. Further information can be found on the Perks page.
The Gunsmith feature allows players to customize each gun with up to five attachments, camouflage, reticle, charm, and sticker. The camouflage, charm, and sticker are all aesthetic and have zero impact on the weapon. The reticle is the dot or design on optics, and can affect gameplay. Attachments have a large impact on weapon performance, and will show the different in the weapon stats.
Attachments are unlocked by using the gun and increasing that weapon’s level. Most weapons can unlock five different attachments along the top half of the gun (Muzzle, Barrel, Laser, Optic, Stock) and four different attachments along the bottom half of the gun (Underbarrel, Magazine, Rear Grip, Perk). There are exceptions to the available attachment slots.
There is no rear grip attachment on the Model 680, FiNN LMG, EBR 14, Crossbow, SKS, Dragunov, or HDR.
There is no muzzle attachment for the AS VAL.
There is no magazine attachment for the P90, Mk2 Carbine, or Kar98k
There is no undebarrel attachment on the bottom half of the Mk2 Carbine.
All handguns have four attachments on the top half, but the Renetti and Sykov have five attachments on the top half because of their Stock attachment slot.
One popular customization in past Call of Duty games that showed player skill was weapon paint. Camouflage will paint the entire weapon skin a specific pattern: spray paint, woodland, digital, dragon, splinter, topo, tiger, stripes, reptile, skulls, and completionist. Each section contains a small list of weapon paints that are unlocked by completing challenges, but first the section must be unlocked by reaching a specific weapon level by using that firearm.

Complete All Camo Challenges
Special camos are awarded for the completionists out there. The gold camo is unlocked after completing 10 different weapon camo challenges, the platinum camo will be unlocked after earning gold camo on all weapons in an entire weapon category (e.g. assault rifles), and the Damascus camo is earned after unlocking platinum camo on all weapons in the multiplayer. Recently the Obsidian camo was made available to Modern Warfare. To unlock Obsidian camo, the Gold camo must first be unlocked on that weapon, then a weapon challenge must be completed specific to that weapon category, and in some cases the actual weapon itself.
Blueprints can be created or unlocked for weapons to save a weapon mod – the equipped attachments and custom aesthetics. Purchased Blueprints will allow players to use a weapon or attachments even if the weapon has not been unlocked through rank progression. Using the gun in-game will still increase the weapon level, but new attachments cannot be used until the weapon is unlocked. All currently owned Blueprints can be seen in the Armory section of the Multiplayer menu.
