The Missing Link DLC已经在Steam上供应下载，加点心得，标题留着...

Baos

看来这次的DLC发售时间是按照所有时区的18日零点算的，理论上应该可以下载，估计和BRINK原理类似...希望有人能提供文件...
可能需要破解，按照GameFAQs会员的总结此扩展是在Steam上分开启动，可能是两个程序...大小2.1 GB...

Update: 再加一条，Steam的Deus Ex Human Revolution版区讨论帖中Bad_Motha简短的解释了一下此扩展的简单细节...帖子中同时确认大小为2.1 GB...

It is a stand-alone, but still requires the original game files to actually launch.
It works in the same manner as Ep:1 and Ep:2 for Half-Life2.

So if you launch DX:HR, that will just launch the original game (along with any DLC content from Explosive and/or Tactical packs, if you have those). Launching DX:HR Missing Link however, just loads that and only that. As it has it's own stand alone story-line.               

大概翻译: 扩展利用单独程序，并且只载入The Missing Link自身，不过仍然需要原版游戏文件，和HL2的EP1以及EP2类似...原版还是使用之前的程序...

Update 2: 官方DLC页面已经改成Available Now，剩下的估计不必多说了...

Update 3: 有一个1.3.643.1补丁，看来需要破解两个EXE...

简短总结: 这个DLC剧情有了，跌宕起伏有了，商店有了，选择有了，阴谋也有一点，不过长度只有3小时，还得是Standalone模式...Credits很长，看不看完无所谓，因为后面没有剧情花絮...最后的"We hope you stick around, because we're just getting started..."，感觉要走Fallout的路...有一些隐藏要素，还有Burke's Revolver...弹药不算紧张，经验也很多，大概20+个Praxis升级点数...

P.S: 看了下成就，Factory Zero是个挺麻烦的东西...
