Uncharted 3: Drake's Deception has shipped 3.8 million copies worldwide on the day of its release, according to a statement from Sony.
No data has yet been made available regarding actual sales, but Sony notes that the game is on track to become the biggest selling game in the Uncharted series to days, and one of the best-selling releases this year.
"Uncharted 3 is a blockbuster and these incredible sales figures reflect that. Consumers are clearly as eager to play the game as critics were to heap praise upon it," says SCEE head of communications Nick Caplin.
"The team at Naughty Dog deserve this fantastic reception at retail. The Uncharted series, exclusive to PlayStation 3, has redefined the third-person adventure genre and is now one of the leading franchises available."
