Microsoft has unveiled details of its TV advertising campaign for Halo 3 – as well as a teaser of what fans can expect.

According to the publisher, the promotional clips will bring the game’s ‘epic battles to life in the style of a museum “diorama”’.

The ad hits UK TV screens next Tuesday, at 21.35pm, but fans can get a sneek peek at the ad by visiting www.xbox.com/halo3 from today.

The advert does not focus on the specifics of the graphics or gameplay, but instead looks at the themes that lie at the heart of the tale that spans the entire Halo trilogy.

Microsoft says that the ‘diorama’ featured in the ad is a ‘100 per cent accurate replication’ of a battle taken from the Halo universe.

At over 400 sq ft in surface area, reaching a height over 12ft above the ground and with each handcrafted human figure standing 8 inches high, it was large enough to fill an entire studio at Stan Winston, the Los Angeles modelmakers responsible for the creature models from films such as Aliens and Jurassic Park.

The 90-second short took director Rupert Sanders and his team four days.

Head of Gaming and Entertainment at Microsoft UK Stephen McGill said: “It’s amazing to see such the legendary world of Halo brought to life in such a creative way through the construction and filming of this ad.

"I’m sure the epic shots and dramatic scenes in the commercial will be a hit with Halo fans and newcomers to the franchise alike, giving them just a taste of what they have to look forward to when the game comes out on September 26th.”
