Does Mafia 2 Have Online Multiplayer on Xbox Live?

No. Mafia II (2010) on Xbox 360 is a strictly single-player game. It has no multiplayer modes—online, split-screen, or co-op.

What It Offers

• Linear, story-driven campaign (~10–12 hours).
• Open-world Empire Bay (1940s–50s) for exploration between missions.
• DLCs (Jimmy's Vendetta, Joe's Adventures, Betrayal) add side stories, still single-player.

Multiplayer Mafia Games

• Mafia III (2016): Single-player only.
• Mafia: Definitive Edition (2020): Remake of Mafia I, single-player.
• GTA Online / Red Dead Online: Open-world crime co-op/PvP.
• The Godfather II (2009): Had multiplayer (defunct).

For a narrative mafia experience, Mafia II is excellent—just play it solo.
