COD4 reaches 11 million unique players on Xbox Live
Infinity Ward's Rob Bowling revealed during his acceptance speech at the BAFTAs last Tuesday night that Call of Duty 4 has raked-in 15 million unique online players since launch.
The split is heavily skewed towards Live.
"I'm delighted that we just reached 11 million unique players on Xbox Live and we've got over 4 million on PSN," Bowling said.
Xbox Live has 17 million users overall, according to Microsoft, meaning that two-thirds of users have played the game.
Just to compare, World of Warcraft has 11 million active players worldwide.
No numbers were given for PC users.
