[[quote]]"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."[[/quote]]
PAYDAY: The Heist is very much like Left 4 Dead, and very different at the same time. Left 4 Dead has players fighting against wave upon wave of zombies as they make their way through each level. PAYDAY, however, has players performing heists on banks, locating the bank manager or simply storming the bank and holding their ground as cops and special forces units attempt to take them out.
