We already found out last week that Valve will soon start offering Mac games. Shacknews has now learned a little more about the company's cross-platform plans, and as it turns out, Mac gamers will get access to Valve's entire library of games, "including Left 4 Dead 2, Team Fortress 2, Counter-Strike, Portal, and the Half-Life series."
Mac gamers won't have to wait long, either; Valve quotes an April time frame. Knowing how the company has historically stuck to self-imposed schedules, though, we wouldn't be surprised to see that slip.
But wait, there's more! The Shack says future Valve games like Portal 2 will come out for both Windows and Mac OS X at the same time, and more importantly, buying one Valve title will entitle you to copies for both platforms. That means PC gamers will be able to start Steam up on their MacBooks and install, say, Team Fortress 2 without having to shell out another dime, to name one scenario.
Shacknews' quotes from Valve staff mention the addition of OpenGL support to Valve's Source engine. There's also this little tidbit from Portal 2 lead developer Josh Weier: "Checking in code produces a PC build and Mac build at the same time, automatically, so the two platforms are perfectly in lock-step." In other words, it looks like Mac gamers can expect native ports—no emulation shenanigans there. The Mac and PC versions will be able to join the same multiplayer games, too.
