Valve has slammed "sh*tty" motion control party-games - and, despite expressing interest in Project Natal, has pledged never to place a 'tiresome' mini-game for the device in Left 4 Dead.
Speaking exclusively to CVG ahead of the release of Left 4 Dead 2 DLC The Passing, Valve writer Chet Faliszek said that the studio believes Project Natal is "really cool" - but begged other developers not to waste the opportunity it presents.
"Hopefully we've gotten past the point of mini-games," he said. "I'm sick of that [makes arm movement]. That's not a game for me anymore. Let's get some real interaction going.
"We have these technologies now that let us interact in different, really exciting ways. It's developers' jobs to do something with it. Impress me. Don't just make sh*tty games I wouldn't want to play if I had to use a joystick."
When asked if Valve was looking to put Natal compatibility in any of its future Left 4 Dead games, Faliszek added:
"We'll see. You won't have to make the arm movement of sawing off a zombie's head in some tiresome mini-game. I can promise you that."
