The Sacrifice

The Sacrifice is the 2nd DLC to Left 4 Dead, which depicts how the L4d1 survivors meet the l4d2 survivors in The Passing. it is Downloadable for Left 4 Dead and Left 4 Dead 2, but is only playable as the L4D1 survivors.

Gameplay
Players can play as Louis, Zoey, Bill, or Francis. You navigate through a port to raise a bridge and get to a ship. You can find items from L4D2 along the way, allowing you to use l4d2 guns and of course, melee weapons. it is a 3 map campaign, and ends with one of the players sacrificing themselves to raise the bridge for the other 3 survivors, who survive.

Reviews
Michael- a good dlc which is even better than the passing, has good environments, and the "player sacrifice" feature is good, but when that player dies it looks like they didnt put any effort into the scene. 4/5 stars...
