Bethesda's Fallout is one of just four IPs to have sold more than half a million units in a week in the UK.
Fallout 4 smashed the 500,000 barrier, generating more than 24m in revenue, and that's without counting digital sales via Steam, PSN or Xbox Live.
The data, courtesy of GfK Chart-Track, revealed Fallout 4 is the 18th fastest-selling game in terms of units (behind Black Ops III) and the 16th fastest-selling game in terms of revenue (behind FIFA 11).
Last week was a bumper week for UK games retail overall. 54.6m was generated from the sale of boxed releases, making it the biggest seven days of sales this year. It's a welcome boost to the sector, which has suffered so far in 2015. Fallout 4, second-week sales of Call of Duty: Black Ops III and the arrival of Rise of the Tomb Raider means that the market is now just down 0.5 per cent so far this year (by revenue).
We wanted to bring customers an unforgettable experience for what was expected to be the release of the year,” said GAME UK retail MD Charlotte Knight.
Launch night certainly didn't disappoint, we saw tens of thousands of fans arriving at midnight openings across the UK.”
HMV games buyer Nathan Allen added: We had a great week – Fallout performed incredibly well. It was also encouraging to see that COD had a strong second week.”
Fallout merchandise was also a major seller over the period. ShopTo commercial boss Alison Fraser said: The iconic brand is so loved that we created our own ShopTo Exclusive Edition full with Fallout 4 merchandise, plus we sold many other single items to complement the big release. It's a well-deserved triumph for Bethesda.”
Games Centre's Robert Lindsay added: Sales on Fallout merchandise saw the highest attach rate we've had on a launch to date.”
