Left4Dead Blog: June 15th Update - Nightmare, What do Zombies think?

Nightmare
You’ll never see them coming

This Survival Mutation was inspired by Karma Jockey. There are commons, plenty of beefed up Specials, no glows, and lots and lots of fog. If you like to be scared by things that jump out at you from the night, this one is for you.

What do Zombies Think?
While cleaning/moving our offices around (all our desks at Valve are on wheels so we can have desk races), we discovered this old, long ago used Zombie decision making tree. It was created before our session with Mike Patton to record the common zombie sounds. While it is near indecipherable gibberish thanks to bad penmanship, it shows not at an AI level how a zombie behaves but all the speech opportunities and transitions.

Our favorite is the top. Lay Down? Nope. Want to vomit? Sure.

Useless update again. No bug fixes, no map updates, zero news about Cold Stream or ported bug fixes to the Xbox 360 version.

But oh, THEY HOLD DESK RACES.

What I can make out is, the top row, first box, looks like it says "kill human". Second box, first row looks like "setup" or "getup".

Second row, first box, "lay down". Second box... maybe "continue to lay/lay down". Not sure.

Third row is easy. First box-"vomit?". Second box-"vomit".

Fourth row, first box, "see human?". Second box, "kill!".

I'm not even going to try the fifth row. First one says, "*something* *something* near"... and that's all I can make out.
