PRE-ORDER LEFT 4 DEAD, PLAY THE DEMO FIRST
Xbox 360 and PC Pre-Order Includes 10% Savings Plus Advance Demo Access
  October 28, 2008 -Valve, creators of best-selling game franchises  (Half-Life, Portal, Team Fortress, and Counter-Strike) and leading  technologies (Steam and Source), today announced a special promotion  granting those who pre-order Left 4 Dead early access to the official  demo.  
  Left 4 Dead is the new survival action game from Valve that blends the  social entertainment experience of multiplayer games such as  Counter-Strike and Team Fortress with the dramatic, narrative experience  made popular in single player action game classics such as the Half-Life  series of games.  
              Early access to the demo begins Thursday, November 6 on both  the Xbox 360(r) video game and entertainment system from Microsoft and  the PC. This pre-order promotion applies to all Steam PC pre-orders and  all Xbox 360 and PC pre-orders from participating retailers in North  America. The demo will feature single player and co-operative modes,  supporting 1 to 4 player games.   
  On November 11 the demo will be made available to all Xbox 360 and PC  and  gamers, with no obligation to purchase. The demo concludes on  November 18, when Left 4 Dead will be made available at retail outlets  across North America and worldwide via Steam.   
              This pre-order promotion is scheduled in concert with the  previously announced $10 million consumer launch campaign that spans  television, outdoor, print, and online advertising.   
              "Every time someone plays Left 4 Dead, we witness the most  overwhelmingly positive reaction that we've seen from any of our games,"  said Gabe Newell, president and co-founder of Valve. "This gives us  tremendous confidence in the product and why we've taken the game on the  road, produced this pre-launch demo, and invested more advertising  dollars on the title than any prior release from Valve."   
              Playable in single player, co-operative, and multiplayer  modes, Left 4 Dead is one of the most anticipated releases of 2008 and  winner of numerous pre-launch awards, including Best of E3 from multiple  outlets.
