GAME has seen "amazing demand" for the new Xbox 360 250GB.
The videogame retailer opened 400 stores at midnight for the release of Microsoft's "whisper quiet" new Xbox 360.
"At midnight, over 400 GAME and Gamestation stores opened across the UK to allow our customers to get their hands on the new Xbox 360," Neil Ashurst, head of PR for GAME and Gamestation, said.
"There has been amazing demand for the new version of this ever-popular console, which includes a new slim design, 250GB hard drive and built-in WiFi connectivity. There was a fantastic atmosphere in our stores as hundreds of people queued to be one of the first to play on the new console."
Microsoft announced the new Xbox 360 250GB during its press conference at E3 2010 last month. It costs £200 in the UK.
The new Xbox 360 has already done the business in the US, where it helped sales rise by a whopping 88 per cent year-on-year.
