在内华达州沙漠，美国陆军在一个古老的'外国人墓'附近建立了一个军事基地，并且经过多年的努力已成功地打开它。4名幸存者听说了这个军事基地的传言。但是对坟墓并没有什么了解，也不知道他们抵达后会怎样。。。

地图介绍：
Hi guys!
After more than a year working on my L4D1 campaign, One 4 Nine, I've now released it.
One 4 Nine is a four-level campaign for Left 4 Dead 1. The setting is the Nevada Desert. The U.S. Army have built a Military base around an ancient 'alien tomb', and after years of trying have finally managed to open it. The four survivors - Francis, Bill, Zoey and Louis - have heard rumors of a fortified safe zone located in the U.S Army's base, but have no knowledge of the tomb, nor what will await them upon arrival.
Note, this version is only single player and coop, not versus. I'm currently working on adding versus mode, and some survival maps too.
Enjoy. Feedback and bug reports are very welcome, either here or by email to info@one4nine.co.uk

嗨，大家好！
经过我在L4D1战役一年多的工作，一4九，我现在已经把它公布了出来。
一4九是Left 4 Dead 1(求生之路1)的战役地图，故事背景是内华达沙漠。美国陆军在一个古老的'外国人墓'附近建立了一个军事基地，并且经过多年的努力已成功地打开它。四名幸存者“弗朗西斯(Francis)，比尔(Bill)，佐伊(Zoey)和路易斯(Louis)”听说了这个坚固的美国军事基地所在区的传言，但是对于那个坟墓没有了解，也不知道他们抵达时将有什么等待着他们。。。
请注意，这是一个单人战役地图，不是对抗。我目前正在研究加入对战模式，和一些生存模式的地图了。
