GIve up your life for your friends

Valve has announced that they will be discounting the PC and Mac versions of Left 4 Dead and Left 4 Dead 2 by 66 percent on Steam to celebrate the launch of The Sacrifice DLC.

The Sacrifice is a full pack of DLC that will be available as a free update for Mac and PC gamers and is compatible with both Left 4 Dead and Left 4 Dead 2.

Xbox 360 gamers will also be able to purchase the pack on Xbox Live Marketplace later on today.

The Sacrifice is a prequel to The Passing DLC pack and follows the L4D survivors as they head South. It also adds a new gameplay dynamic that allows one player to give their life so that the other three can escape during the finale.
