Valve is launching a massive advertisement campaign valued at $10 million for its upcoming co-op focused first-person shooter Left 4 Dead later this November, according to an Edge report. Beginning November 9 through the 28th, a series of commercials that mix “humor and horror” will be shown on popular television networks such as ABC, ESPN, Fox, MTV, Comedy Central, USA, and Spike TV.

Additionally, Left 4 Dead billboards will be placed across a number of populated U.S. cities, including New York, Chicago, Boston, Seattle, Los Angeles and San Francisco.

According to Valve co-founder Gabe Newell, retail pre-orders are up a whopping 60 percent from Orange Box. Pre-orders on Steam will open up later next week, with the full game launching on Xbox 360 and PC November 17.
