Warzone Legacy Weapons are the guns from Modern Warfare II through Black Ops 7. From Season 1 on November 6, 2026, they sit in the Legacy tab of the Loadout menu and cannot be edited in Gunsmith. Each gets a fixed five-attachment version, and these setups start locked until you unlock them through Player XP in the Armory.

Only MW4 weapons keep Gunsmith and Mastery Camos, and our MW4 weapon leveling covers those guns, not Legacy unlocks. The facts below come from Activision’s November 2 Warzone Season 1 post and its September 24 Carry Forward post.

How Warzone Legacy Weapons unlock in the Armory

  1. Open the Legacy tab. Activision says all weapons from MWII through BO7 stay accessible there, in the Loadout menu.
  2. Earn Player XP. Activision says these setups unlock through Player XP in the Armory.
  3. Unlock the setup you want. Two kinds of setup are locked at first: the five-attachment version of each base weapon, and any Legacy Blueprint with its existing attachments.

Activision has not published how much Player XP each unlock needs, whether unlocking uses up XP, or the unlock order. All of that is Not confirmed. For what else changed at launch, see our Warzone Season 1 patch notes guide.

Does the Player Level reset or Multiplayer XP affect Armory unlocks?

Activision says the reset lets you “level up and optionally Prestige across Multiplayer, DMZ, and Call of Duty: Warzone”. It does not say how that reset affects Armory progress, or whether XP from Multiplayer or DMZ counts toward Armory unlocks. Both are Not confirmed. Our guide to leveling up fast in MW4 lists the confirmed XP sources for MW4 itself.

What Legacy Weapons can and cannot do in Season 1

FeatureLegacy Weapons

Activision does not list the five attachments for any weapon. It also does not say whether a Legacy gun with no attachments can be used before you unlock anything.

Do Warzone camos carry forward to Legacy Weapons?

Blueprints do, but camos do not. Activision corrected its own September post on this point, saying it was wrong to state that Weapon Camos from legacy titles would be available. Operators, Operator Skins and Weapon Blueprints from MWII, MWIII, BO6 and BO7 carry forward.

Calling Cards, Emblems, Finishing Moves, Emotes, Sprays, Parachutes and Contrails also carry forward, according to the November 2 post. Our older guide on whether Warzone camos carry over to MW4 has the background. If other players’ older skins bother you, the Operator Skin Toggle changes what you see.

Should you use Legacy Weapons or MW4 weapons in Warzone?

Activision says MW4 weapons “provide the full weapon experience” and that it wants the meta to feel “distinctly rooted in Modern Warfare 4”. Each of the 33 launch weapons, plus the Season 1 additions, has Weapon Prestige and Warzone Mastery Camos. So if you chase camos, you need MW4 weapons. Our Warzone Mastery Camos guide lists the challenges.

That is a design goal, not a damage comparison. Season 1 stats for Legacy Weapons are not published, so we cannot say which guns stay competitive. Raven Software says it will balance weapons on a biweekly basis, so any early ranking may move quickly.

Frequently asked questions

Are old guns removed from Warzone in Season 1?

No. Activision says all weapons from MWII through BO7 stay usable in the Legacy tab.

Can you use Gunsmith on Legacy Weapons?

No. They use a fixed five-attachment version or an existing Blueprint’s attachments.

How much Player XP does a Legacy Blueprint need?

Not confirmed. Activision says only that they unlock through Player XP in the Armory.

Do I keep the Blueprints I paid for?

Activision says the Skins and Blueprints you earned and purchased remain available. It also says Legacy Blueprints start locked and unlock through Player XP in the Armory. So you can keep ownership and still face an in-game unlock step. How that works for paid items is Not confirmed.

Do Legacy Weapons support Warzone Mastery Camos?

No. Activision lists Mastery Camos among the features they do not support.
