先粘贴经过我整理的游民文章：
　　曾任《半条命》系列的前任编剧之一的Marc Laidlaw似乎是在自己的博客上发布了一段提纲，将戈登·弗里曼和其他人物在《半条命2》第三章中的遭遇进行了交代，一起来了解一下。
　　在Marc Laidlaw发布博文后不久他的博客就因为流量爆炸而导致浏览困难，有玩家将这部分提纲复制到了Pastebin网站上。当然没人能保证这就是真正的“第三章”，不过也的确有些蛛丝马迹能够证明其合理性。比如在2013年时就曾有“消息人士”处的传闻称，第三章的保密协议在2017年时就会到期，而该消息人士早先“泄露”的内容，至少是在一部分上与Laidlaw本次发布的内容是相吻合的。
　　接下来我们来说说这部分帖文的内容，首先必须说明一下，全文很长，笔者对《半条命》的剧情并不熟悉，所以无法给大家全部翻译。除此之外，各位也要谨慎选择是否要了解这部分剧情，从某种程度上来说，这也是严重剧透了。
　　全文以一封信的形式展开，以戈登·弗里曼的口吻向玩家们揭示了第二章之后发生了哪些故事。首先，弗里曼提到，在Eli Vance死后，抵抗组织遭受重挫，不过最终在Eli Vance勇敢的女儿Alyx Vance强韧的意志鼓舞下，他们又再次团结起来。长期与Eli共事的助手Dr. Judith Mossman传回了极地的坐标，弗里曼等人相信这就是研究船北极光号（Borealis）所在的位置。Eli Vance一直坚信“北极光号”必须被摧毁，不能让它落入联合军手中。但团队中其他成员并不同意，他们认为北极光号中可能藏有能够帮助革命成功的秘密。不过弗里曼表示，在找到北极光号之前，这一切讨论也没有意义。因此，在埋葬了Eli Vance之后，弗里曼和Alyx登上了一艘水上飞机去寻找“北极光号”。
　　在寻找“北极光号”的过程中，弗里曼遭遇了Wallace Breen。他并没有死，或者是从某种角度来说他是没死。联合军将他较早前的意识保存了下来，Breen过去的人格被安置到了一个Grub（蛆，蠕虫，大概就是联合军文明的本体的那个形象）当中。Vallace表示自己其实是联合军的囚犯，他恳求弗里曼终结他的生命。Alyx认为让Vallace速死是便宜了他，不过弗里曼还是偷偷动了些手脚来加快Vallace的死亡，结束他的痛苦。
　　不久之后他们发现了被关押的Judith Mossman，Judith表示自己其实是服务于反抗军的双面间谍，尽管Alyx并不信任甚至依然憎恨她，不过弗里曼依然选择与Mossman博士合作。在经过非常曲折的过程之后，弗里曼博士一行人最终找到了“北极光号”，Alyx坚称自己已经向亡父发誓自己一定会摧毁“北极光号”，她已经在船上设置了自爆装置，“北极光号”会驶向联合军的核心爆炸。Judith反对她的决定，她冲向“北极光号”想要解除Alyx的设定，不过却被Alyx直接射杀。
　　最终Alyx和弗里曼乘上“北极光号”冲向联合军指挥中心的核心执行自杀式行动，但是在过程中，G-Man出现在了Alyx Vance的眼前，“现在跟我来，我们有地方要做有东西要去”（Come along with me now, we’ve places to do and things to be），Alyx跟着G-Man离开，留下弗里曼博士眼睁睁地随着“北极光号”驶入联合军的指挥中心爆炸。他看到了联合军强大的力量、自己的努力是如何徒劳，他看到了一切，最主要的就是“北极光号”号，这艘原本能够反抗军最强大武器的研究船，最终是如何徒劳无功地炸成碎片。
　　不过弗里曼最终没有死于这场爆炸，弗地冈人将他从船只上来了出来扔到了一边。在信的最后，弗里曼感叹，老朋友们要么销声匿迹，要么已经折戟沉沙，他不再认识、认可大多数研究团队的成员，尽管他相信着反抗的精神依然存在。他期待着“你能采取比我更为恰当的行动，我把这交给你了”，而这就是弗里曼的最终章。

以下粘贴原文 没兴趣的可以跳转至4楼：
I hope this letter finds you well. I can hear your complaint already, “Gordon Freeman, we have not heard from you in ages!” Well, if you care to hear excuses, I have plenty, the greatest of them being I’ve been in other dimensions and whatnot, unable to reach you by the usual means. This was the case until eighteen months ago, when I experienced a critical change in my circumstances, and was redeposited on these shores. In the time since, I have been able to think occasionally about how best to describe the intervening years, my years of silence. I do first apologize for the wait, and that done, hasten to finally explain (albeit briefly, quickly, and in very little detail) events following those described in my previous game (referred to herewith as Episode 2).
To begin with, as you may recall from the closing paragraphs of my previous missive, the death of Eli Vance shook us all. The Resistance team was traumatized, unable to be sure how much of our plan might be compromised, and whether it made any sense to go on at all as we had intended. And yet, once Eli had been buried, we found the strength and courage to regroup. It was the strong belief of his brave daughter, the feisty Alyx Vance, that we should continue on as her father had wished. We had the Antarctic coordinates, transmitted by Eli's long-time assistant, Dr. Judith Mossman, which we believed to mark the location of the lost luxury liner Borealis. Eli had felt strongly that the Borealis should be destroyed rather than allow it to fall into the hands of the Combine. Others on our team disagreed, believing that the Borealis might hold the secret to the revolution’s success. Either way, the arguments were moot until we found the vessel. Therefore, immediately after the service for Dr. Vance, Alyx and I boarded a seaplane and set off for the Antarctic; a much larger support team, mainly militia, was to follow by separate transport.
It is still unclear to me exactly what brought down our little aircraft. The following hours spent traversing the frigid waste in a blizzard are also a jumbled blur, ill-remembered and poorly defined. The next thing I clearly recall is our final approach to the coordinates Dr. Mossman has provided, and where we expected to find the Borealis. What we found instead was a complex fortified installation, showing all the hallmarks of sinister Combine technology. It surrounded a large open field of ice. Of the Borealis itself there was no sign…or not at first. But as we stealthily infiltrated the Combine installation, we noticed a recurent, strangely coherent auroral effect–as of a vast hologram fading in and out of view. This bizarre phenomenon initially seemed an effect caused by an immense Combine lensing system, Alyx and I soon realized that what we were actually seeing was the luxury liner Borealis itself, phasing in and out of existence at the focus of the Combine devices. The aliens had erected their compound to study and seize the ship whenever it materialized. What Dr. Mossman had provided were not coordinates for where the sub was located, but instead for where it was predicted to arrive. The liner was oscillating in and out of our reality, its pulses were gradually steadying, but there was no guarantee it would settle into place for long–or at all. We determined that we must put ourselves into position to board it at the instant it became completely physical.
At this point we were briefly detained–not captured by the Combine, as we feared at first, but by minions of our former nemesis, the conniving and duplicitous Wallace Breen. Dr. Breen was not as we had last seen him–which is to say, he was not dead. At some point, the Combine had saved out an earlier version of his consciousness, and upon his physical demise, they had imprinted the back-up personality into a biological blank resembling an enormous grub. The Breen-grub, despite occupying a position of relative power in the Combine hierarchy, seemed nervous and frightened of me in particular. Wallace did not know how his previous incarnation, the original Dr. Breen, had died. He knew only that I was responsible. Therefore the grub treated us with great caution. Still, he soon confessed (never able to keep quiet for long) that he was herself a prisoner of the Combine. He took no pleasure from her current grotesque existence, and pleaded with us to end his life. Alyx believed that a quick death was more than Wallace Breen deserved, but for my part, I felt a modicum of pity and compassion. Out of Alyx ’s sight, I might have done something to hasten the grub’s demise before we proceeded.
Not far from where we had been detained by Dr. Breen, we found Judith Mossman being held in a Combine interrogation cell. Things were tense between Judith and Alyx, as might be imagined. Alyx blamed Judith for her father’s death…news of which, Judith was devastated to hear for the first time. Judith tried to convince Alyx that she had been a double agent serving the resistance all along, doing only what Eli had asked of her, even though she knew it meant he risked being seen by her peers–by all of us–as a traitor. I was convinced; Alyx less so. But from a pragmatic point of view, we depended on Dr. Mossman; for along with the Borealis coordinates, she possessed resonance keys which would be necessary to bring the liner fully into our plane of existence.
We skirmished with Combine soldiers protecting a Combine research post, then Dr. Mossman attuned the Borealis to precisely the frequencies needed to bring it into (brief) coherence. In the short time available to us, we scrambled aboard the ship, with an unknown number of Combine agents close behind. The ship cohered for only a short time, and then its oscillations resume. It was too late for our own military support, which arrived and joined the Combine forces in battle just as we rebounded between universes, once again unmoored.

What happened next is even harder to explain. Alyx Vance, Dr. Mossman and myself sought control of the ship–its power source, its control room, its navigation center. The liner’s history proved nonlinear. Years before, during the Combine invasion, various members of an earlier science team, working in the hull of a dry-docked liner situated at the Aperture Science Enrichment Center in Lake Huron, had assembled what they called the Bootstrap Device. If it worked as intended, it would emit a field large enough to surround the ship. This field would then itself travel instantaneously to any chosen destination without having to cover the intervening space. There was no need for entry or exit portals, or any other devices; it was entirely self-contained. Unfortunately, the device had never been tested. As the Combine pushed Earth into the Seven Hour War, the aliens seized control of our most important research facilities. The staff of the Borealis , with no other wish than to keep the ship out of Combine hands, acted in desperation. The switched on the field and flung the Borealis toward the most distant destination they could target: Antarctica. What they did not realize was that the Bootstrap Device travelled in time as well as space. Nor was it limited to one time or one location. The Borealis, and the moment of its activation, were stretched across space and time, between the nearly forgotten Lake Michigan of the Seven Hour War and the present day Antarctic; it was pulled taut as an elastic band, vibrating, except where at certain points along its length one could find still points, like the harmonic spots along a vibrating guitar string. One of these harmonics was where we boarded, but the string ran forward and back, in both time and space, and we were soon pulled in every direction ourselves.
Time grew confused. Looking from the bridge, we could see the drydocks of Aperture Science at the moment of teleportation, just as the Combine forces closed in from land, sea and air. At the same time, we could see the Antarctic wastelands, where our friends were fighting to make their way to the protean Borealis; and in addition, glimpses of other worlds, somewhere in the future perhaps, or even in the past. Alyx grew convinced we were seeing one of the Combine’s central staging areas for invading other worlds–such as our own. We meanwhile fought a running battle throughout the ship, pursued by Combine forces. We struggled to understand our stiuation, and to agree on our course of action. Could we alter the course of the Borealis? Should we run it aground in the Antarctic, giving our peers the chance to study it? Should we destroy it with all hands aboard, our own included? It was impossible to hold a coherent thought, given the baffling and paradoxical timeloops, which passed through the ship like bubbles. I felt I was going mad, that we all were, confronting myriad versions of ourselves, in that ship that was half ghost-ship, half nightmare funhouse.
What it came down to, at last, was a choice. Judith Mossman argued, reasonably, that we should save the Borealis and deliver it to the Resistance, that our intelligent peers might study and harness its power. But Alyx reminded me she had sworn she would honor her father’s demand that we destroy the ship. She hatched a plan to set the Borealis to self-destruct, while riding it into the heart of the Combine’s invasion nexus. Judith and Alyx argued. Judith overpowered Alyx and brought the Borealis area, preparing to shut off the Bootstrap Device and settle the ship on the ice. Then I heard a shot, and Judith fell. Alyx had decided for all of us, or her weapon had. With Dr. Mossman dead, we were committed to the suicide plunge. Grimly, Alyx and I armed the Borealis, creating a time-travelling missile, and steered it for the heart of the Combine’s command center.
At this point, as you will no doubt be unsurprised to hear, a Certain Sinister Figure appeared, in the form of that sneering trickster, the G-Man. For once he appeared not to me, but to Alyx Vance. Alyx had not seen the cryptical schoolmarm (no male equivalent) since childhood, but she recognized him instantly. “Come along with me now, we’ve places to do and things to be,” said the G-Man, and Alyx acquiesced. She followed the strange grey man out of the Borealis, out of our reality. For me, there was no convenient door held open; only a snicker and a sideways glance. I was left alone, riding the weaponized luxury liner into the heart of a Combine world. An immense light blazed. I caught a cosmic view of a brilliantly glittering Dyson sphere. The vastness of the Combine’s power, the futility of our struggle, blossomed briefly in my awareness. I saw everything. Mainly I saw how the Borealis, our most powerful weapon, would register as less than a fizzling matchhead as it blew itself apart. And what remained of me would be even less than that.
Just then, as you have surely already foreseen, the Vortigaunts parted their own checkered curtains of reality, reached in as they have on prior occasions, plucked me out, and set me aside. I barely got to see the fireworks begin.
And here we are. I spoke of my return to this shore. It has been a circuitous path to lands I once knew, and surprising to see how much the terrain has changed. Enough time has passed that few remember me, or what I was saying when last I spoke, or what precisely we hoped to accomplish. At this point, the resistance will have failed or succeeded, no thanks to me. Old friends have been silenced, or fallen by the wayside. I no longer know or recognize most members of the research team, though I believe the spirit of rebellion still persists. I expect you know better than I the appropriate course of action, and I leave you to it. Except no further correspondence from me regarding these matters; this is my final episode.
Yours in infinite finality,
Gordon Freeman, Ph.D.

从原文中可以看到一些硬科幻细节
The staff of the Borealis , with no other wish than to keep the ship out of Combine hands, acted in desperation. The switched on the field and flung the Borealis toward the most distant destination they could target: Antarctica.
光圈的人为了不让船落在联合军手中，所以把船的传送坐标瞄向世界上最南的地方。
What they did not realize was that the Bootstrap Device travelled in time as well as space. Nor was it limited to one time or one location.
空间传送也造成了时间传送，甚至使船在任何时间和地点上都有出现的概率。是不是很像量子态~ 不知道北极光号的概率云会不会扩散...
One of these harmonics was where we boarded, but the string ran forward and back, in both time and space, and we were soon pulled in every direction ourselves.
戈登他们找到的只是在其中的一个时间的一个地点的北极光号。

Time grew confused. Looking from the bridge, we could see the drydocks of Aperture Science at the moment of teleportation, just as the Combine forces closed in from land, sea and air. At the same time, we could see the Antarctic wastelands, where our friends were fighting to make their way to the protean Borealis; and in addition, glimpses of other worlds, somewhere in the future perhaps, or even in the past. I felt I was going mad, that we all were, confronting myriad versions of ourselves, in that ship that was half ghost-ship, half nightmare funhouse.
总之，时间和空间都变得混乱，主角们可以同时体会到过去和未来的自己之类的。那我就想知道，这个结局是不是只是戈登他们在无数时间选择中的一种情况而已？

最后还是用船做自杀式袭击了。
I was left alone, riding the weaponized luxury liner into the heart of a Combine world. An immense light blazed. I caught a cosmic view of a brilliantly glittering Dyson sphere. The vastness of the Combine’s power, the futility of our struggle, blossomed briefly in my awareness.
戈登冲进了联合军世界，被联合军科技的强大震撼了，感觉赢不了。这其中提到了戴森球，难道联合军是能利用全部恒星能量的II型文明？区区II型文明就没信心打了，士官长都要急得跳脚。

人物剧情部分在一楼说的很清楚了，我就不说了。我基本是借助机翻来看的，希望英语大神指正与补充。另附另一个新闻：
　　想让G胖数3是不太可能了，所以粉丝们宁愿自己动手了。如同曾经同人游戏的“黑山基地（Black Mesa）”一样，“北极光行动（Project Borealis）”就是由粉丝自制的《半条命3》项目，该项目的剧情根据从V社离职的编剧Marc Laidlaw此前公布的《半条命2》第三章的剧情为大纲。
　　“北极光行动”将由虚幻4引擎来制作，制作团队现在公开了游戏的首批截图，主要展示了游戏内的建模。

什么是北极光行动？
“北极光行动”是根据“半条命2”编剧马克·莱德劳（Marc Laidlaw）所作的情节，对“半条命3”的故事进行了一番粉丝诠释。我们的目标是提供Marc对HL2情节内容的最佳表达，以符合HL系列的预期。该团队旨在将半条命宇宙带入具有改良图形的现代化发展环境，同时保留半条命2的原始风格和手感。
你在用什么引擎？
为了跟上现代科技的发展，为了发展更高效的流程，我们选择了使用虚幻引擎4.我们知道这可能是一个问题，但是，考虑到Source的年代和它的笨拙，我们相信我们可以使用UE4做出更好的游戏。
我可以加入团队吗？
我们有很多人问我们是否需要他们，简短的回答是：是的，也许吧。开始的时候，我们有一群热心的球迷想要帮忙，后来我们进行了一次主要的招聘活动，在那里我们填补了很多必要的地方。但是，这并不意味着没有希望。我们知道，随着时间的推移，人们来来去去，为了反映这些变化，我们需要引入新成员来填补空缺的角色。留意本站点，我们的subreddit或我们的不和服务器，以找出我们有什么可用的。
我在游戏行业没有任何经验，我还可以申请吗？
虽然PM团队目前专注于邀请高级团队成员来满足特定的技术需求，但我们鼓励在其他工作领域或学术背景下拥有相似技能的人员申请。
你是从头开始/为什么不使用源资产？
我们从头开始，是的。我们将重新创建Source Engine的“感觉”，包括运动，物理和AI等。我们不能真正将这些东西从Source中移植出来，然而，我们的程序员正在努力创造一种我们都习惯的感觉。对于这些资产，大部分的书信3在北极，这意味着很多下雪的资产将不得不作出来，因为Source中现在很少存在。而且已经有十年了，我们觉得他们应该有一点点！
我在哪里可以看到你的进展？
正如你可能在subreddit和现在这个网站上看到的，我们发布了一个更新，包括一些艺术品，模型和早期的音乐曲目。这是我们将根据我们的进展更新您的格式。偶尔回来看看一些很酷的新东西！
你的团队有多大？
在撰写本文时，该团队目前有60多名活跃的开发人员，全力以赴地完成任务。这包括作家，程序员，关卡设计师，游戏设计师，艺术家和声音团队。
你如何管理如此庞大的团队？
仅仅。开玩笑！有一个由5名项目经理组成的团队来协调团队。他们安排会议，指派团队负责人，以确保不断的沟通，有时涉及自己。这确保了每个人都能及时了解正在做什么和需要做什么。
会有什么创意自由？
书信给我们留下了很大的空间来添加某些东西，或者确实删除了一些东西。我们将加入并带走我们认为
正确的
故事，并使事情变得更好。别担心，事情不会改变，故事也不会无法辨认！
5个项目经理？
是的，5！由于这是一个粉丝项目，我们很多成员都在世界各地，因此为了解决时区差异，一般的在线/离线冗余以及为了增加工作量，我们招募了5名成员以确保需求得到满足。
会不会有新的武器和敌人？
有关这方面的细节将会随着发展的进展而发布，但是，不要担心，我们不会因为想法而发疯，所以不要期望任何时候有火箭拳！
你会使用从第3集泄露的内容？
我们不断地提及，看看那些被泄露的东西，然而，我们也在问自己，为什么他们不被包括在内，我们怎么能改进。这并不是说我们直接抛弃，但是，我们正在向他们学习。
配音怎么做？
在一个理想的世界里，我们可以招募原来的弗吉尼亚人，都在一家酒吧见面，并且记录几行，握手并做好，但事实并非如此。当然我们很乐意和原来的VA一起工作，不管这个事情是否会发生，还有待观察。我们将在未来公布更多的细节，包括可能的角色试镜，我们不能填补。敬请关注！
下一步是什么？
正如我们第一次更新中所述，我们目前正在为大家演示一个演示，以获得关于我们如何在新引擎中执行的反馈。您的反馈非常重要，因为这将有助于我们走向未来的正确方向！一定要检查有关演示更新，以及其他任何事情！
结束语
总之，PB团队非常高兴能够在这个项目上工作。我们已经看到了社区的大力支持，导致越来越多的行业专业人士加入我们的行列。敬请期待更多来自北极光行动的新闻！

居然不是坟

原文里面有几处很可疑的地方啊，还有巴尼又龙套了？

猜测：弗里曼三部曲完结，G-man带走Alxy，
从所以半条命4开始的新三部曲主角是Alxy，
玩家将操作Alxy进行游戏。

我擦，竟然不是坟?!不说别的，这个剧本还不错，虽说结局蛮悲惨，毕竟这个故事本身就比较悲惨，半条命1不是说是gman的测试吗

其实关键的问题是，“联合军”这个外星文明离地球相当遥远，也就是没有这些时空链接作为传送，他们也到不了地球上，而且他们自己似乎也并不是那么擅长制造这种链接，我们可以理解为虫洞吧。。。。第一章要塞爆炸的时候是他们的机会没了，其实只要防止他们再次链接到地球上，应该还是能打的。
自从链接没有了以后，他们其实在地球上也是相当疲惫了，我觉得还是可以打的，等关掉链接，清理完地球上的各种Xen的生物，和弗地冈人一起发展文明，只要不爆发双种族在地球上的内战，等人类和弗地冈人发展壮大后，返攻“联合军”不是梦。

第三章最后 Gman把艾利克斯带走了， 留下了弗里曼，虽然弗里曼也没死，但是事情并没有完结，而且由于半条命的世界观非常之大 制作后续作品的切入点非常多应该是易如反掌， 半条命2 第3章之后 完全可以继续出个半条命3。

想问下 半条命3和portal有关联吗？ 还是说里面的关联只是彩蛋？
