PlayStation 3 exclusive Uncharted: Drake's Deception shipped an impressive 3.8 million units worldwide on release day.
"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," said SCEE's 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."
Yesterday Activision announced that Modern Warfare 3 was its biggest game launch ever, but did not release actual sales figures. Analysts Sterne Agee recently predicted 5.5 to 6 million day one sales for the title.
