Today, a beta version of Portal 2, one of the most successful game titles poduced by Valve and generally one of the most successful computer games, has been released for Linux. While the first Portal has been available on Linux for a year now, Valve was working on other titles for Linux, like Left 4 Dead 2, Dota 2 or the new game consoles “Steam machines”, before releasing Portal 2 for Linux.
After announcing a new Linux-based operating system, Valve has recently presented the hardware for the "expansion of the Steam universe".
On the one hand, the company has explained its hardware strategy for the coming game devices „Steam Machines“ for the living-room. On the other hand, a new innovative controller to control these "machines" has been presented.
Today, Dota 2 has finished the beta phase. It is now free-to-play and will be published soon for Linux, after the Linux test phase ran out.
