Valve to deliver Steam and Source for Mac

I rarely post PR releases verbatim, but this one deserves it:

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.

Incredible news. I’ll dissect this as soon as it’s sunk in!

  • “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.”

    That’s the apex of this press release because it adds some legitimacy to Mac as a gaming platform. Mac gaming really needed a shot in the arm. Valve’s visibility and popularity may be the best source for it.

    I love the idea of shared lobbies, servers, etc., but I wonder how many Mac users will be disadvantaged, particularly in FPSs, if they stick to the Apple-branded mice.

    Anyway, outstanding news.

    This is good news for mac gaming. Steam will be able to provide a centralised location for the many small indie mac developers out there and give them a well known platform to advertise and sell their products on. As for larger companies it gives them an easier way of getting mac versions of their games sold, this may even encourage more large developers to actually create mac games if they see that it can be profitable. All of this does of course hinge on mac gamers using steam, which some (myself not included) find irritating to use and release dates/pricing.
