In the past we've shipped features that came from community suggestions. Now we've taken it one step further: we're shipping game content that was directly built by the community.



Today's TF2 update includes a bunch of new items and weapons, all of which were made by members of the TF2 community and uploaded to the Contribute! site. The overall quality of submissions we're receiving is fantastic, by the way, so there'll be plenty of new additions to follow. The submitters of these items will find nifty unique versions sitting in their backpacks, so they can show everyone their work.



This is really exciting for us here at Valve. Starting from our core belief that entertainment products should be services, we've tried to increase the set of ways our community can impact our games, and the ways in which we can reward you for it. From the implementation of features requested by players and mapmakers, to unique community items given to valuable community contributors, to the purchasing and shipping of popular maps, to the ARG-style product announcement of Portal 2, we've tried to include our players in the ongoing challenge of improving our games and their communities.



This update represents the next step in that process. The line between developers and players is getting very blurry, and we think that's a great thing.

Updates to Team Fortress 2 have been released. The updates will be applied automatically when your Steam client is restarted. The major changes include:

Yesterday, we announced that Steam and all our Source engine games will be coming to the Mac. Sound too good to be true? Well, guess what: It is true! There are no catches! Sometimes life actually works like that. The bad news is that we've just truth bombed your hard-earned lie detector back to the stone age, and you'll probably lose all your money to the next international lottery scam that sneaks through your spam filter. Still, Steam on the Mac!



Since we're getting a lot of email asking the same basic questions, we figured we'd just answer them here:



Q: I own TF2 on the PC. Do I have to buy it again on the Mac?

A: No. If you own TF2 on the PC, you own TF2 on the Mac (and vice versa). You don't have to buy the game twice. In addition, the Steam Cloud will automatically propagate your configuration settings and custom sprays to your Mac for you.



Q: Is it just some crappy emulated version of TF2?

A: No! Also: How dare you! Mac users aren't getting a crappy emulated version of the game. TF2 will run natively on OSX, like an actual big boy game for adults.



Q: Hmm, that all sounds pretty good. But I'll bet I can't play with my friends who own Macs if I'm on my PC.

A: Mac and PC users will all play together, on the same servers. We're not creating two separate universes. We're all going to be one big, happy family with guns locked in a bloody, never-ending struggle for cap points.

Left 4 Dead 1 and 2 are coming to the Mac!



We like the platform wars in the forums so much that we've decided to add a new platform to the fray. Later this spring, we'll be releasing both Left 4 Dead 1 and 2 on the OSX operating system for Mac computers, all through Steam.







Steam on the Mac will behave just like Steam for Windows, but through Steam Play will add cross-platform ownership. That means if you own Left 4 Dead 2 for Windows, then you already own it for the Mac. There's no need to buy it twice! Unless you want to buy it twice, in which case, as long as you're feeling so generous, why not buy it five times?



Plus, Mac and Windows players can go head-to-head, since both Left 4 Deads are cross-platform compatible. Mac owners can even host their own servers and create their own maps, just like Windows users.



The Mac Versions of L4D1 and 2 don't run under emulation software but in native code. That's technical talk for how cool your friends will think you are with your five copies of Left 4 Dead 2 for the Mac.



We'll be releasing the exact system requirements soon. The Mac versions will be updated in sync with the Windows versions, so the platform wars can continue uninterrupted.



Even though Left 4 Dead 2 is the only game you'll ever need on any platform, as a purely academic exercise, you should probably check out the complete catalog of games available on the Mac when the Steam client is released in a few weeks.
