Ranking Up in Call of Duty 4: Modern Warfare Without Xbox Live

You do not need Xbox Live Gold.

Call of Duty 4: Modern Warfare (2007) on Xbox 360 uses a **local profile rank system** for offline modes:

• Single Player Campaign: Completing missions unlocks ranks (Private → General) and achievements **offline**.
• Split-Screen / System Link Multiplayer: Earns XP, ranks up, unlocks weapons/attachments/camos **without Xbox Live**.
• Barracks / Create-a-Class: Fully accessible offline.

What Requires Xbox Live Gold

• Xbox Live Matchmaking (Public lobbies, Ranked Playlists).
• Leaderboards (Global stats).
• DLC Map Packs (Variety, Creek, Strike, etc. — delisted, unbuyable now).

Modern Context (2024)

• Xbox 360 servers for CoD4 **are still online** (as of 2024) but population is <50 players peak.
• Xenia (PC Emulator) + XLink Kai / System Link over VPN allows "LAN" play over internet without Gold.
• CoD4: MW Remastered (2016) on PS4/Xbox One/PC requires PS Plus / Gold / No sub (PC) for MP.

Bottom Line: Pop in the disc, play offline, rank up to 55 / Prestige 10 (if you have time) — no subscription needed.
