The campaign will also promote Nintendo's handheld DS Lite console, and aims to target one million consumers through a UK-wide interactive tour showcasing the new console's capabilities.
The tour will take in shopping centres, theme parks, airports, exhibition halls, leisure centres and universities across the UK until the spring, and will target an audience aged "five to 95", according to the agency, from experienced gamers to complete beginners.
Nick Rankin, managing director at BD-NTWK, said: "[Wii] is taking the sector out to a much wider audience than ever before. As a result we've had to think hard about developing a strategy which is as inclusive as possible while also delivering a range of different sampling experiences that will resonate with the different audience segments within our target."
Wii is Nintendo's seventh generation console and the successor to the Nintendo GameCube, and is being acclaimed for its wireless controller, which can detect three-dimensional movement.
Wii is released in the UK and the rest of Europe on December 8.
