Can You Play GTA 4 Multiplayer Without Xbox Live?

No

Grand Theft Auto IV multiplayer (Free Mode, Team Deathmatch, Race, Cops 'n Crooks, etc.) is entirely online and requires an Xbox Live Gold subscription (or Game Pass Ultimate).

Why

• Rockstar Games Social Club handles matchmaking, but the underlying network layer on Xbox 360 is Xbox Live.
• No LAN, System Link, or splitscreen multiplayer exists in GTA IV.
• Single-player story mode is fully playable offline.

Alternatives for Offline Multiplayer

• GTA V (Xbox 360/One/Series) – No local multiplayer either.
• GTA: San Andreas (Xbox/PS2/PC) – Two-player rampages (PS2/Xbox only, not 360 BC).
• Saints Row 2 (Xbox 360) – Full co-op campaign via System Link/Online (Gold required for online).
• Red Dead Redemption (Xbox 360) – Free roam multiplayer (Gold required).

For any online multiplayer on Xbox 360, Xbox Live Gold is mandatory.
