Halo 4 takes flight

Halo 4 takes over London's skies.

Celebrating the launch of one of the year's most highly anticipated games a 'Halo 4' Glyph symbol -- 50 foot in diameter -- was flown over the British capital.

Becky Hicks travelled from Kent to see the spectacle.

SOUNDBITE: Becky Hicks, fan, saying (English):

"We went to this special event by London Bridge, I am here because I really enjoy Halo."

Halo 4 is the start of a new saga in the highly popular Halo franchise.

The game went on sale at midnight across 40 countries.

In London fans waited eagerly outside a retailer to be among the first to get a copy.

In 2004 Halo 2 set a record as the biggest entertainment launch ever with day one sales bringing in over $125 million U.S. dollars.
