If you're going to be in the San Diego area on the 23rd, you may want to stop by the San Diego Comic Con and score some points in Valve's zombie apocalypse simulator. Who knows, it might come in handy when the dead really start walking the earth.

Anyway, just to be clear, the Xbox 360 version of Left 4 Dead 2 (also on PC) will be playable at the San Diego Comic Con for the duration of the event. You can try it out July 23 to 25 from 2 to 9PM and July 26 from 12 to 5PM at EA's Gaming Lounge at the Hilton San Diego Gaslamp Quarter Hotel.

Since the Con is still more than a week away, here's a new screenshot from Left 4 Dead 2's Swamp Fever campaign level. That's the map that will be featured in the playable demo, by the way. It seems to be a showcase for the AI Director's new weather control features.
