All Modern Warfare II weapons will be available for Modern Warfare III players, although each weapon’s associated unlock challenge must be completed before it becomes accessible in MWIII. Any Blueprints also carry forward, and certain MWII Blueprints available via Store Bundles will also be available to purchase in MWIII.
Some Base MWII weapons were available for a limited time during MWII’s Seasons of content, and are initially inaccessible to MWIII owners, unless the specific Weapon Unlock Challenge for that weapon has been completed.
To reiterate: If you haven’t played MWII and pick up MWIII, the full complement of MWII weapons will be available, but only after the associated weapon challenges in MWIII are completed.
Therefore, Modern Warfare III players should expect the following Base weaponry accessible in the Gunsmith, at launch:
Example 1: The Base M13B Assault Rifle (above) is available to obtain only during DMZ, after defeating the Chemist boss character (or defeating another player carrying the Base M13B) and exfilling with the weapon. If obtained in this manner, the Base M13B becomes available to use (and level up) in MWII and MWIII.
Example 2: The Blueprint M13B Assault Rifle “Naughty” (above) is available to obtain only via the Store Bundle “Tracer Pack: Klaus Operator.” If purchased in MWII, the Blueprint (but not the Base) M13B becomes available to use (and level up) in MWII and MWIII.
COD MW3 Bot Lobby, Boosting, Accounts
All Modern Warfare II attachments will be available in Modern Warfare III and can also be used on MWIII weapons, assuming they are attachable to the weapon in question.
All Weapon Camos will carry forward into Modern Warfare III. Limited-time Event Camos that were available only during a certain period are accessible if you unlocked them in Modern Warfare II at that time.
Example 1: A MWII player has an M4 with “Orion” Mastery Camo unlocked (above). They can equip the weapon, and the Camo, and any other unlocked Camos in MWIII. Note you can’t equip the “Orion” Camo to a MWIII weapon (see Question 10).
Example 2: A MWII player has the universal Camo “Dark Bones” (above) that was earned during the MWII Season 03 Reloaded Camo Event. They can equip this Camo to any MWII weapon, providing they unlocked it during the time of the Event. Note that “universal Camo” now means “universal to MWII weapons”
UPDATED INFORMATION: Yes for Base Camos.
Modern Warfare II Base Camos can be equipped on Modern Warfare III weapons, and vice versa. However, Completionist Camos (Gold, Platinum, Polyatomic, and Orion) can only be applied to the MWII weapons you’ve completed the unlock for, and cannot be applied to MWIII weaponry.
Note: MWIII is set to include its own expansive set of Camos, including completionist Camos (separate from the MWII Gold, Platinum, Polyatomic, and Orion, above). These MWIII Camos cannot be earned for MWII weapons.
Weapon progression will continuously update between games.
Example 1: Leveling up the M4 (shown above) in Modern Warfare III will also level up the weapon in Modern Warfare II (and vice versa). This includes unlocking all the weapon attachments (if applicable) as well as Camos and mastery Camos.
Example 2: If a MWII player has a set of weapons still requiring Weapon XP (WXP) to level up (to unlock attachments and/or Camos), this can be done in either MWII or MWIII. However, regular Player Rank and Prestige XP (unrelated to WXP) would be awarded to the specific game in question.
Yes, provided the tactical or lethal is accessible and available for use in MWIII.
You would be able to have some or all of your Modern Warfare II weaponry arsenal fully leveled up and unlocked, along with their associated Camos, ready for Modern Warfare III launch, providing you put in the appropriate time to unlock and level up this content in MWII, prior to – or even after – playing MWIII.
