Lighthouse Finale

"Lighthouse Finale" is the second and final chapter of "The Last Stand" Left 4 Dead 2 campaign.

The Survivors start off in a safehouse adjacent to a military outpost settled in a firetower near the lighthouse.

Outside the safehouse, the survivors must pass an overrun military outpost. From here, they must fight their way to the lighthouse. They find that the lighthouse, despite in dilapidated state and without means to contact help, is still working. The survivors managed to turn on the lighthouse generator. The combination of bright light and the lighthouse's alarm glare will summon large hordes of infected. The survivors must defend themselves against the infected while they wait for rescue.

Halfway through the finale, the generator runs out of fuel. The survivors must hastily collect fuel cans (the amount changes between difficulties) to turn the generator back on. Once they do, depeding of the difficulty, either one or more Tanks will arrive shortly after. After the said Tanks have been killed, a small fishing boat catches the lighthouse signal and the survivors must go down to the seaside from the lighthouse, where it waits to pickup the survivors. Multiple tanks may spawn during this stage. After all survivors board the boat, the boat will drifted away from the shoreline to the misty island far away from the mainland, and the camera pans to the lighthouse.

Trivia

 * It is unknown if the lighthouse depicted in both Left 4 Dead and Left 4 Dead 2 is based on a lighthouse in real life in the USA. However, the lighthouse building itself might be modeled after the Presque Isle Light on the shore of Lake Erie in North Western Pennsylvania. It is one of three lighthouses in Erie, along with the Erie Land Light and the North Pier Light. The lighthouse is situated on the northern shoreline of Presque Isle State Park overlooking the beach.
 * This map is largely based on the original "Lighthouse" map from Left 4 Dead's "The Last Stand", but extended to cover the military outpost building outside and the seaside under the lighthouse.
 * There is presence of military facility (and infected servicemen). However, no trace of CEDA suggest that the lighthouse and the nearby village were solely under the protection of military before they were finally overrun by The Infected.
 * At the top of military outpost tower there is a foot locker. When opened, a AK-47, a Magnum Pistol, and a Silenced Submachine Gun with unique skins can be found.
 * Near the lighthouse, there is a small cabin. In here, one can find a body of a deceased survivor holding a pitchfork.
 * Although the map is placed in non-canonical timeline, the ending of this map ironically resembles and fulfills Bill's plan to get away from the U.S. mainland to remote island to ensure his and the rest of the L4D1 survivors' safety. In the canonical story, Bill dies before his plan is realized. Although Zoey, Francis, and Louis finally managed to escaped to the Florida Keys in aftermath of "The Passing".
 * Originally, in the original L4D1 version of this map prior its final version, a video showed that instead of turning on the generator you were supposed to use a radio to call for help instead. This was cut in the final version anyway. The concept, apparently revived with much darker way in this map. At the same cabin where you can find a deceased survivor and pitchfork, there is a non-functioned radio located here. However, since the radio is not working, the desperate survivor tried to fixed it but all to no avail, resulting him to fell into insanity and committed suicide (see the graffiti). This might influence the L4D1 survivors decision to light the lighthouse instead to calling the help.
 * If you looked carefully the maps in the military outpost tower, the maps actually the same maps used in Blood Harvest's Farmhouse Finale.
 * If you go to the right instead passing straight the military outpost from the safehouse, there is a stretch of road but blocked with a bus wreck in the end. The bus model is the same bus model that appear in Death Toll's The Church.
