Left 4 Dead 2 demo code diggers did indeed unearth the names of two bits of DLC for Valve’s upcoming ZFPS. Just don’t get too excited by the news -- they were fake names, created as a bit of test code in order for the demo to clear Microsoft certification stuff.

This information comes via Valve’s Chet Faliszek, who spoke about the DLC during a Eurogamer-sponsored event this afternoon.

“If you’re reading in the forums and you’re reading about the ‘Miracle’ DLC or whatever, that’s test code,” he said, according to Kotaku. “To get tested through Microsoft certification we had to do test scenarios with DLC.”

“We haven’t actually come out internally with what we’re going to do yet.”

Faliszek’s words end that little mystery, but there’s still a few more to explore. Like, for example, why these latest survivors even bother with leaving their safe rooms. It seems like the wise choice during a zombie infestation is to sit and cry in a corner until it ends. Perhaps the code has an explanation for this somewhere in its innards.
