Call of Duty: Modern Warfare 2 on Wii? No, It Wasn't Released

No. Call of Duty: Modern Warfare 2 (2009) released on:

• PlayStation 3
• Xbox 360
• PC (Steam)

The Wii received Call of Duty: Modern Warfare – Reflex Edition (2010), a port of the first Modern Warfare (2007) with Wii Remote controls. It did not get MW2.

Wii's hardware couldn't handle MW2's engine; Activision focused on HD consoles/PC.
