This is awful if it's canon to Left 4 Dead, the PayDay characters are huge starfishs. They're basically trying start the Green Flu outbreak, haha.
Nevermind:
Valve's Chet Faliszek has emailed us, saying that the YouTube video isn't a prequel, that it was "just some over-excited marketing guys."
"This is a 100% Overkill made mission for Payday: Heist simply set in no mercy hospital from the Left 4 Dead series. It is not telling the origins of the Infection and is not canon. There is a little cameo from one of the L4D characters (the comic should give you a hint) and a fun little easter egg with a payoff later in Left 4 Dead. Just us having some fun with a studio we are friends with and who have also made a great co-op game."
No doubt the cameo in this DLC will be Bill.
