The Docks

"Well--better get moving. Remember, if you fall behind, Bill thinks it's okay to let you die."

"Hey Louis, I don't think it's a tank in there. It sounds like a puppy. You should stand closer."

The Docks is the first chapter of The Sacrifice campaign. The Survivors have escaped from Millhaven with their lives, but with the sacrifice of many. Putting their disputes aside for now, the Survivors follow the plan to find a sailboat to travel to the Florida Keys, where safety and sunshine lie in wait.

Campaign
Most Left 4 Dead players familiar with the tightly confined landscapes of earlier campaigns will find this a relatively straight-forward "run 'n gun" level since there is plenty of open space in which to maneuver, long vistas and good sunlight. Moreover the Common Infected mostly appear in open sight or are located in intuitively predictable locations: all of which simplify combat operations and even enable fast players to move ahead without bothering to engage non-threatening Infected milling around on the peripheries. A good idea is to conserve primary weapon ammunition, which is more useful for unexpected hordes and Special Infected, by making maximum use of Pistols and throwable items to clear Common Infected out of your path.

Navigate by looking for red road flares, vehicle headlights and associated "through here" visual and audio cues. The level is an industrial landscape richly endowed with opportunities for teams to detour away from the main line of approach in order to explore.

New to the Left 4 Dead series is Explosive Barrels - a combination of Gas cans and Propane tanks. They generally come in sets of two, and although unmovable by Survivors, can do massive damage to Infected lurking close by.

Along the way the Survivors will run into a locked train car containing an angry Tank. In order to complete this Chapter it is necessary to pass through the train car and so one Survivor must volunteer to unlatch the door and release the Tank. Not surprisingly, letting the Tank out also spawns an Infected horde into a combat area lacking in cover and protective angles. (If possible keep Pipe bombs or Bile bombs handy for the horde and focus the team's initial defensive fire onto the Tank.)

Versus
Important note on Tanks! Tanks do not have the frustration meter in L4D2 Versus so starting the Tank that is in the armored train car will not cause the Tank to die. Possibly an attempt to prevent an exploitable advantage.

Survival

Setting it lose was the only choice they had, but with the Tank's roars calling every nearby infected to the yard, will the Survivors have a chance to escape?


 * This map has every type of weapon including: four chainsaws, the M60 and the Grenade launcher.


 * Due to this map having CEDA worker infected, Bile bombs are very common and will spawn alot, despite in Dead Center them spawning rarely. So don't hesitate to use them!


 * This being a small map, it doesn't really have many defendable positions so improvisation and teamwork is what will get you the high medals. Try to arange your weapons in one area so they're easier to get at.
 * Gas cans and Propane tanks should be put in several locations around the map to allow cutting off of the horde giving you breathing space and time to deal with Tanks!
 * The group Achievementor have made a video showing this map in Survival mode to go with their new series "Surviving the Apocalypse" in which they essentially show videos of each Survival map in action.

Behind the Scenes

 * Due to the first Left 4 Dead and Left 4 Dead 2 having different graphics, the fog and dark tones are noticeably greater in the version on the first game in comparison its counterpart on the sequel.
