Valve have officially announced the release of Steam for Linux, following months of beta testing. The client is now available to download from the Ubuntu software Centre.
To celebrate, Valve are holding a sale on all Linux games until 5AM AEDT on February 22. You can pick up Amnesia: The Dark Descent for $5, the original Half-Life for a paltry $2.50, or Bastion for just $3.75, among others.
Team Fortress 2 players who play from their Linux installs of the game will receive a free Tux item for use as well, so get cracking! That offer is only valid until the end of the month.
