HALF-LIFE™ COMING TO SEGA DREAMCAST™
Best-Selling, Critically Acclaimed Action Thriller Heads to Sega's Next Generation Console

BELLEVUE, WA (February 14, 2000) - Sierra Studios™ and Valve LLC today announced at the Milia trade show in Cannes, France that their award-winning action thriller game, Half-Life, is currently in development for a summer release on Sega Dreamcast. Half-Life combines great storytelling with intense action and advanced technology to create an impressive, realistic world where players need to think smart to survive. Originally created for the PC by Valve, Half-Life has won more than 50 Game of the Year awards from publications around the world, was named "Best PC Game Ever" by Imagine Media's PC Gamer magazine (November 1999), and has sold over 1.5 million copies worldwide.

In development by Northern California-based Captivation Digital Laboratories in conjunction with Gearbox Software and Valve, Half-Life: Dreamcast is set to be even more extraordinary than the original PC version. The Sega Dreamcast edition will feature several optimizations, including higher polygon player characters, dramatic lighting and special effects, to showcase the power of the Sega Dreamcast and deliver a fresh and exciting player experience for console gamers.

Half-Life: Dreamcast will also feature an all-new single player mission that surrounds the Black Mesa Security Guard character, Barney. This special mission is being custom created for the Dreamcast by Gearbox Software, the Texas-based development team that created Half-Life: Opposing Force™, the official PC expansion for Half-Life and runner-up to 1999 Game of the Year by PC Gamer magazine (March 2000).

"Half-Life has become a big franchise with 1.5 million units sold worldwide," said Hubert Joly, CEO of Havas Interactive. "Its immersive environment, the depth of its story, its unique action character lend themselves well to creating a great console product that takes advantage of the high performance of the Sega Dreamcast."

"Valve's number one objective is to deliver state of the art entertainment experiences that push the envelope with every new release," noted Gabe Newell, co-founder and managing director, Valve. "By partnering with Sega our intention is to create an incredible new version of Half-Life that takes full advantage of Sega Dreamcast's architecture."
