Valve's popular video game distribution and social platform, Steam, finally arrived on Linux with a closed beta on Tuesday.
Steam is a well-loved hub where PC gamers can peruse and purchase games, often at significant discounts, and engage with one another socially by playing games and chatting.
Valve initially promised only a bare-bones version of Steam for Linux, but the platform launched on Tuesday with around two dozen games and bells and whistles that include the "Big Picture" mode that makes it easier to game on large displays like televisions.
Notable games available Tuesday on Steam for Linux included Team Fortress 2, Amnesia: The Dark Descent, Superbrothers: Sword and Sworcery EP, and Serious Sam 3: BFE.
Curiously absent was Left 4 Dead 2, the game many expected to see on Linux after Valve talked it up in July.

Valve issued a call for "experienced Linux users" in late October, seeking 1,000 interested parties to help test out Steam for Linux.
But instead of a mere 1,000 would-be Linux gamers, the Bellevue, Wash.-based game developer heard from 60,000 respondents.
With so much interest, Valve promised that the beta will open up to more users soon, according to Polygon.
The initial Steam for Linux beta was only available on Ubuntu 12.04, but Valve developer Frank Crockett reportedly promised that more distros would arrive soon, as well.
Down with Windows?
"This is a huge milestone in the development of PC gaming," said Valve CEO Gabe Newell, according to Polygon.
"Steam users have been asking us to support gaming on Linux. We're happy to bring rich forms of entertainment and our community of users to this open, customer-friendly platform."
Valve released Steam for Mac OS X in 2010, making Steam for Linux the third version of the gaming platform to be released.
Linux is far from the most popular operating system, but with Valve's help getting gamers invested the platform could gain users in the future.
