Overkill Software"s October 2011 multiplayer first person shooter PAYDAY: The Heist has become a solid downloadable sales hit for the PC and PS3. In April, it was revealed that the game had sold 400,000 units. Overkill was recently acquired by Starbreeze and the company confirmed at that time that expansions to the original PAYDAY, along with a full sequel, were in the works.
Today, Overkill"s website revealed that it will be working with Valve on a new project that could see PAYDAY and Valve"s co-op themed zombie shooter Left 4 Dead merge. Here is the statement:
As perceptive gamers will have noticed, several hints have recently been dropped into PAYDAY The Heist, which has led to various rumors. We are excited to be able to confirm that an in-depth collaboration between OVERKILL and Valve is currently in production. We are working on a very cool blend of PAYDAY and Left 4 Dead. I am sure it is so exciting that it will have some players check into the hospital before we are done.
The original Left 4 Dead was released in 2008, followed by the sequel, Left 4 Dead 2, in 2009. In 2010, campaigns for Left 4 Dead 1 and 2 were released that linked the storyline and characters of both games.
