The Sacrifice

The Sacrifice is a DLC campaign for Left 4 Dead^[Clarify] and a built-in campaign for Left 4 Dead 2. While originally slated for release only as a L4D campaign, The Sacrifice was delayed over five months and eventually released for both games.

The Left 4 Dead 2 version of the campaign includes all of the new weapons and special infected featured in the game. Additionally, the original Left 4 Dead characters models were ported over for the campaign, and new dialogue was recorded for them.
