新近泄露到网络上的《求生之路2（Left 4 Dead 2）》成就列表，为我们揭示了几项官方尚未公布过的新情报，其中包括新的战役名和新的游戏内道具。

在这50项成就中，有两个名字格外引人注目，一个是“死点（Dead Center）”，一个是“暴雨（Hard Rain）”。这也证实了之前公布的游戏海报上有关新战役内容的推测。

除此之外，还有两个新道具名出现在了X360版成就列表中。首先是“狂暴驱逐炸弹”，推测为一种能够驱赶或诱导丧尸的手榴弹。其次是“二次电击”，估计是用来拯救频死生还者的医疗道具。

当然，现在对这些道具用途和使用方法的分析只是猜测，实际情况恐怕只能等玩到游戏后才能知道。另外，对50项成就内容感兴趣的同学，可以到下面地址查看。
