Valve to Deliver Steam & Source
on Mac

Leading Gaming Service Expands to
Mac Platform

Valve announced today it will bring
Steam, Valve’s gaming service, and Source, Valve’s gaming engine, to the Mac.

Steam and Valve’s library of games
including Left 4 Dead 2, Team Fortress 2, Counter-Strike, Portal, and the
Half-Life series will be available in April.

"As we transition from entertainment
as a product to entertainment as a service, customers and developers need open,
high-quality Internet clients," said Gabe Newell, President of Valve. "The Mac
is a great platform for entertainment services."

"Our Steam partners, who are
delivering over a thousand games to 25 million Steam clients, are very excited
about adding support for the Mac," said Jason Holtman, Director of Business
Development at Valve. "Steamworks for the Mac supports all of the Steamworks
APIs, and we have added a new feature, called Steam Play, which allows customers
who purchase the product for the Mac or Windows to play on the other platform
free of charge. For example, Steam Play, in combination with the Steam Cloud,
allows a gamer playing on their work PC to go home and pick up playing the same
game at the same point on their home Mac. We expect most developers and
publishers to take advantage of Steam Play."

"We looked at a variety of methods
to get our games onto the Mac and in the end decided to go with native versions
rather than emulation," said John Cook, Director of Steam Development. "The
inclusion of WebKit into Steam, and of OpenGL into Source gives us a lot of
flexibility in how we move these technologies forward. We are treating the Mac
as a tier-1 platform so all of our future games will release simultaneously on
Windows, Mac, and the Xbox 360. Updates for the Mac will be available
simultaneously with the Windows updates. Furthermore, Mac and Windows players
will be part of the same multiplayer universe, sharing servers, lobbies, and so
forth. We fully support a heterogeneous mix of servers and clients. The first
Mac Steam client will be the new generation currently in beta testing on
Windows."

Portal 2 will be Valve’s first
simultaneous release for Mac and Windows. "Checking in code produces a PC build
and Mac build at the same time, automatically, so the two platforms are
perfectly in lock-step," said Josh Weier, Portal 2 Project Lead. "We’re always
playing a native version on the Mac right alongside the PC. This makes it very
easy for us and for anyone using Source to do game development for the Mac."

Support for the Mac in Source and
Steamworks is available to third parties immediately. Interested developers
