The Last Stand (Left 4 Dead)

The Last Stand is the name given to the "fifth campaign" for Survival Mode only. It has only one map called The Lighthouse. It is possible that Valve is going to release more maps for this campaign for use in Survival Mode. It should be noted that the tagline is "It Doesn't End Well", as Survival Mode always ends in the Survivors being killed.

Strategy

 * A good place to fight the Horde is from the top of the lighthouse on the wraparound walk way. This gives the best line of sight and forces all of the infected to climb up, slowing them down greatly.
 * Having at least one survivor with a hunting rifle is almost necessary given the sight lines available and the constant threat of distant smokers pulling survivors off the roof.
 * Assault rifles also come in handy to shoot the infected and Tanks before they even reach the survivors.
 * Shotguns are extremely useful when Hunters pounce and for clearing out any infected that do make it up to the survivors. However, fighting Tanks from here is a bad idea, as explained later, so using a shotgun against a Tank here is ill-advised. Therefore, having no one with a shotgun is not a bad idea, while having more than one survivor carrying a shotgun is a waste.
 * Molotovs and pipe bombs often start up here. If an ammo run is needed, the best place to run is the roof of the generator room since it requires less climbing and keeps you off the ground.
 * Investing time before the round starts to bring all of the gas cans and propane tanks up to the very top of the lighthouse is a good idea. The best place to keep them is on the highest part of the lighthouse, above the wraparound balcony, to prevent stray bullets from causing the team's death. A sniper perched up here can throw them down and use them when/where needed. However, camping up here makes an easy target for Smokers, so the sniper has to keep moving and be alert.
 * The downfalls to this strategy are the breakable railings and possibility of getting knocked off the roof and killed by the Tank. To avoid these pitfalls, keep moving so Smokers can't drag anyone off the roof and take care to stay away from the edges, where someone might be left helplessly hanging. Also, when Tanks come, it's much wiser to move down to a lower level of the roof as the blind corners and deadly drops give Tanks the only advantages they need.
 * Smokers generally attack from behind trees on the hills located to the survivors left from the start as well as from the ground and lower levels of the roof on the waterfront side of the house. On the hill side, Smokers are extremely difficult to see or shoot, and on the water side they can pull the survivors all the way down to the ground, causing almost certain death for the victim. (The damage doesn't come from the fall but from being pulled so far away from the rest of the survivors.)
 * The best way to fight Smokers is to keep moving, watch for the Smoker's spore cloud, and carry ranged weapons. Good communication with other players is also critical to staying alive.
 * A fun but wasteful idea is to spread all of the gas cans and propane tanks out on the ground around the light house. When the horde comes, throw a Molotov cocktail or pipe bomb down and watch the entire ground be set on fire with intermittent explosions. As before, this is fun to watch but leaves the survivors with no gas cans or propane tanks to fight with.

Trivia

 * The Survivors on this poster look almost exactly the same as they do on the Death Toll poster, aside from a different background and mirror.
 * This is the only campaign that will end in the death of The Survivors.
 * This campaign also currently contains no Safe rooms. The only safe time is the period before activating the horde.
 * The Last Stand is a name of a popular zombie flash game were a survivor and people that he collects along the way try to keep off hordes of zombies from their base, similar to how the Survivors in this campaign must keep off the hordes. This could be a reference to the game.
 * There is no definitive storyline involving the five campaigns in Left 4 Dead, the campaigns can be linked to one another with careful observations but this does not define it as Left 4 Dead canon— although, one could guess that The Last Stand Campaign reveals what ultimately happens to the Survivors.
 * This could be connected to the Death Toll Stage because if you look out into the water you can see a sinking boat, the rescue Vehicle in Death Toll
