Offline Multiplayer Call of Duty Games on Wii: None Exist

No Call of Duty game on Wii offers offline (split-screen/local) multiplayer.

Why

• Design Focus: Wii ports prioritized motion controls and online play; local multiplayer was secondary.
• Hardware Limits: The Wii's GPU/CPU struggled to render two viewports at playable framerates.

Wii CoD Titles (All Online-Only Multiplayer)

• Call of Duty: World at War (2008)
• Call of Duty: Modern Warfare Reflex (2009)
• Call of Duty: Black Ops (2010)

For split-screen/local multiplayer on Wii, look at other genres: racing (Mario Kart Wii), platformers (New Super Mario Bros. Wii), party games (Wii Party).
