Starbreeze Studio's upcoming co-op heist caper Payday 2 is already turning a profit for the studio, despite the game not being out for another week.

 
Preorders of the game have covered the money invested by publisher 505 Games six days before the game's official launch, according to Starbreeze CEO Bo Andersson-Klint. Payday 2 will be released for PC on August 13, with Xbox 360 and PlayStation 3 versions being rolled out later that week.

"Today Starbreeze has once again demonstrated that our strategy of focusing on our own properties is correct,” said Andersson-Klint in a statement (translated from Swedish by Gamechup). “Not only have we managed to deliver a desirable product in Payday 2 but also executed a promotion that few companies of our size can."

“We now look forward to the royalty income that can secure the company’s development of its own IP in the future. That Payday 2 generates revenue for the company six days before the release is of course very unusual for games of this size and strengthens the long-term nature of our strategy.”

Payday 2 lead designer David Goldfarb said in June that Payday 2 would not feature microtransactions.
