Valve Corporation announced in the mid-2000s that they would continue their Half-Life series with episodic expansions of Half-Life 2. Valve released the first two episodes of a supposed trilogy, but have failed to complete the saga or even hint at the third entry's existence.
We wish for the Federal government to order Valve to release their final product on Steam, Xbox 360, PS3, and/or Wii U at their earliest convenience. Steam for Linux can wait.
