Call of Duty: Modern Warfare 2 has generated sales of over $550 million, but how much did the blockbuster video game sequel cost publisher Activision? According to an LA Times report the cost of development and marketing combined was as much as $250 million.

Development is said to have cost in the region of $40 to $50 million, but biggest outlay has been on marketing and the cost of producing and distributing the game discs - a massive $200 million.

The investment looks to have paid off though, with Lazard Capital Markets analyst Colin Sebastian estimating the game will eventually go on to sell 15-20 million units, exceeding $1 billion in sales.
