Valve/Overkill not making Left 4 Dead prequel, making something smaller but "really cool"
Shortly after Payday devs, Overkill, announced that they were working on something with Valve, rumours began to pop up suggesting that that something could be a prequel to Left 4 Dead. That might sound like a promising idea, but it isn't happening. Valve developer Chet Faliszek put a swift "woah, nelly!" on those rumours in a chat with PCGamesN.
"I want to make sure that people don't think the prequel is coming," said Faliszeck. "If that happens, then it will make this other thing we're doing feel uncool, when the thing we're doing is really cool."
Chet described Valve and Overkill's new thing as "kind of akin to how in TF2 you might see some other games' weapons get translated and put into that game."
"We're doing something similar to that, but it's a little bit more involved," he explained.
A character crossover perhaps? Criminal clown masks for Left 4 Dead survivors? Tanks in cop hats? Valve are being discreet. "We're trying to be a little coy and a little fun because we want the communities to discover it," said Chet, "but those guys are still making Payday: The Heist, we're still making Left 4 Dead."
