对于合金装备5幻痛背景故事，大家总是很多争议，网友翻译了一篇最新MGS小说作者在访谈中提到小岛对合金装备5幻痛剧情详解。
背景故事分析
Big Boss’ organization in V is absolutely a band of criminals in the eyes of the world order. They can be viewed as a kind of war mafia, interfering in world conflicts to make money. But it’s hard to see things that way when you’re actually playing the game. Viewed from the outside, everything they do is unacceptably wrong, but playing as them makes you see them as good people. That’s why I really like Huey’s (Emmerich’s) character in V. He always says the perfect thing to make you hate him at just the right time (laughs). He seems like the worst bad guy in the game, but viewed objectively that’s not the case. As a civilian, he’s actually closer to the player than any of the other characters. The things he says actually always make sense, but that just makes you hate him more.
People who’ve played through the game will probably remember the scene in which Huey is exiled from Mother Base, arguably one of the most memorable scenes in the game.
Nojima also cites an email sent to him by Kojima in which he explains some of his intentions with the story of MGSV and the way it ends.
Early video games never had much of a story. Metal Gear was among the first to add story to its gameplay. The player controls Snake, and together we’ve told this story over the years. As the series went on, the player jumped between multiple characters like Solid Snake and Naked Snake, and the story evolved into the legend that is the Metal Gear saga. In this final Metal Gear, it was only right to return the role of Snake, the main character, to the player. It’s saying that from now on, you make the story. It’s saying this is what it means to come full circle and complete a story. If this were a one-way medium like a movie, V’s ending wouldn’t have been possible, but this was a game. This made it possible. Taking a story we’ve told together over the years, and placing it in the hands of the player. That was the real intention behind V.
If the player wasn’t a doppelganger to Big Boss in V, that would have meant Big Boss himself dying later on. And long before V, back in the original Metal Gear, the player (acting as Solid Snake) had in fact killed Big Boss. That made it important for this final instalment that the player once again enters into the story and brings things full circle in their own way. I think it’s only at that point that the story truly belongs to the player. This is “creating the story together with the player,” something that can’t be done in traditional media like movies and books. This can only be done in a video game. That’s what makes V the culmination of everything we’ve always done since the original Metal Gear.
今我游冥冥，弋者何所慕！。

Big Boss的军事组织在游戏的世界里是一个绝对的犯罪组织，他们被认定为战争的黑手党，参与世界的纷争并赚取金钱。但是，一旦你玩过这个系列游戏，你很难认同这种说法。从局外者的视角看，他们所做的一切是错误的，也无法接受，但随着游戏的开展你会发现他们是好人。这就是为什么我真的喜欢Huey博士这个游戏里的角色。他总是说笑道只有在恰当的时间里你才能对他深恶痛绝。他在游戏里就像是最坏的人了，但事情却并非是那样。作为一个人物，他确实比其他人物更贴近玩家，他所说的话确实有道理，但也就是因为这一点，玩家们反而更反感他。那些已经通关了的玩家来说，可能印象最为深刻的是Huey从母基地里驱逐出去的情景，那段争执的话语是最难忘的。
Huey是那个眼镜男博士，是2代Otacon(Hal Emmerich)的父亲。
游戏系列的制作人之间通过电子邮件往来互相谈论过合金装备系列的故事剧情以及这作作为结尾的剧情安排。
早期的游戏之中并没有那么多的故事剧情，合金装备系列游戏是这个时期的游戏里最早把故事剧情贯穿于游戏游玩之中的。玩家们操控snake，同样，制作人们这么多年也在续写故事剧情。随着故事剧情的发展，玩家可操控的人物从固蛇到裸蛇有一定的跳跃性，一直演变成了一部具有传奇色彩的英雄故事。作为系列最终作品，主角当然是回归到snake。这也就是说，从现在开始，你降开创这个故事剧情，你将把所有的故事和剧情联系在一起。如果这种故事用单线式的叙事方式来展现的话，比如电影，这部作品作为结局而言还是不足够的，但，这是一款游戏。靠玩家的游玩可以作为系列的终结，并把这几年来的剧情整合在一起。这是这款作品的最终目的。
这款游戏中，如果玩家操控的这个角色不是big boss的假扮替身的话，那可能big boss本人会在以后的故事中死亡。以至于，在该系列游戏首作品中的固蛇确实已经杀死了big boss。这么设计就让玩家在这个系列最终一部作品中，以玩家游玩游戏的方式挖掘剧情，把之前的故事串联起来。小岛认为也就能以这种方式，让玩家体会到游戏的故事剧情的发展在于玩家自己。这种“玩家怎么玩就会创造怎么样的故事”的方式是传统媒体，像电影和书之类无法比拟的。这也只能通过游戏的方式。这也意味着这部作品会自合金装备系列游戏以来的一个收尾作品。
