Left 4 Dead: The Sacrifice

This digital comic was created by Valve to coincide with the final Left 4 Dead DLC and show us how the stories of the original four survivors began and ended. Over the course of four issues, Bill, Francis, Louis, and Zoey are captured by the military and escape a horrible fate before deciding what their endgame is. It's a fun comic that integrates well with the game, and highlights how good Valve can be at storytelling when they decide to make things.
