MW4 explains progression and Prestige

Two Prestige paths

After level 55, players choose a path before every new Prestige rank. Classic Prestige resets level unlocks and Create-a-Class progress in exchange for 20 percent bonus XP, one permanent unlock token and extra cosmetic rewards. Regular Prestige also restarts at level 1 but keeps all gear and class unlocks.

How far does progression go?

• Multiplayer: 55 regular levels.
• DMZ: a separate 70-level progression track.
• Ten Prestige ranks with rewards inspired by earlier Infinity Ward games.
• Prestige Master then continues to level 1,000.

Weapons and camos

Military and Special camos can be earned in Multiplayer or DMZ and used across both modes. Once a weapon reaches its maximum level, it can enter its own Weapon Prestige path. Some attachments relock, while camos, blueprints and other customization remain available.

Multiplayer and DMZ also receive three mode-specific Mastery camos each. Warzone variants arrive with Season 1.
