Call of Duty 4: Modern Warfare (Xbox 360) - No Bots in Split-Screen

You cannot add CPU-controlled bots to split-screen multiplayer in Call of Duty 4: Modern Warfare on Xbox 360.

The local multiplayer mode is strictly for two human players. There is no option to fill empty slots with AI.

What You Can Do

• Play 1v1 with a friend.
• Play Campaign Co-op? No—CoD4 campaign is single-player only.
• Online/System Link: For larger matches, you need additional consoles/copies.

Later CoD titles (e.g., World at War, Modern Warfare 2, Black Ops series) added combat training / bot support in various forms, but CoD4 does not have it.
