Who is - or was - the boy?

　　Even though the boy reacts to being disconnected from mind control in a similar fashion to the zombified humans you encounter, it's clear that he is different from them. For one, they appear to possess a superhuman level of durability, with them able to fall from great heights without so much as breaking a sweat, whereas the boy would die upon impact. Then there are the extra abilities the boy possesses, such as being able to swim, jump and, later in the game, control the minds of others without the use of a helmet.

　　If the boy is also a test subject, which is hinted at by the secret ending, then he is clearly more advanced than the other experiments he encounters. He even has audible reactions to the events around him, exhibiting shock and fear when confronted by enemies. This suggests that he is at least partially cognizant in regards to his surroundings and actions, unlike the other experiments that litter the factory which behave more like reanimated corpses than actual human beings. If the boy is an escaped test subject, as has been suggested, then it's curious as to why he'd want to return to the factory he has escaped from. This is where the second theory regarding Inside's secret ending comes into play - perhaps the boy is actually being controlled by the blob he becomes swallowed by later in the game.

　　If this is the case, then this would suggest that the switch located in the vault buried beneath the cornfield doesn't disconnect the boy from the player, but rather from the blob. This would then explain why the boy is so keen to venture into the factory and sacrifice himself in order to rescue the blob, with him unplugging it from the cables holding it in place, before it promptly envelopes him and begins rampaging through the factory. With the boy seemingly being an advanced experiment, the blob only gains the ability to effectively escape from his underwater cage when he gains access to the boy's substantial "powers" by swallowing him. As such, the boy appears to merely be a catalyst for the blob's escape.

　　那个男孩是谁-或是-?

　　即使男孩被断开的精神控制在类似的方式被你遇到的人的反应，很明显，他与他们不同。一，它们似乎具有超人的水平的耐久性，他们能够从高处坠落而流汗，而男孩会死后的影响。然后有额外的能力，男孩拥有，如能够游泳，跳跃，并在游戏后，控制别人的头脑，而不使用头盔。

　　如果这个男孩也是一个测试的主题，这是暗示的秘密结局，那么他显然比其他实验中遇到的其他实验。他甚至对他周围的事件有声音的反应，表现出的震惊和恐惧时，面对的敌人。这表明，他对他周围的环境和行动，至少是部分地认识到，与其他实验，垃圾厂的行为更像复活尸体比实际存在的人。如果这个男孩是一个逃脱的测试对象，如已提出的，那么它很好奇为什么他会想回到他已经逃离的工厂。这是第二理论对于里面的秘密结局进场也许男孩实际上是被滴他成为被后来在游戏中控制。

　　如果是这样的话，那么这将表明，开关位于埋在麦田不跳马断开男孩从球员，而是从BLOB。这就解释了为什么男孩如此热衷于冒险进入工厂，牺牲自己来拯救斑点，他拔出它的地方举行的电缆，才及时信封他开始狂暴的工厂。这个男孩似乎是一种先进的实验、BLOB只获得有效地摆脱他的水下笼的能力时，他获得了男孩的实质性的“权力”吞下他。因此，男孩似乎仅仅是一个blob逃跑的催化剂。

　　It's set in the same universe as Limbo

　　A major theory that is validated pretty early on in the game is that Inside is set in same universe as Limbo, Playdead's previous platformer. There are a few of reasons why this appears to be true, with the mind-control slugs that appear around the game's introductory sequences being chief among them. This time around these slugs don't latch themselves onto the player, but rather onto animals - specifically, pigs - with them leaving a slew of dead pig bodies behind. Now, their fondness for pigs rather than humans this time around is likely a result of them being manufactured by the factory for future experimentation upon humans, with pigs actually being used for human medical research in the real world. Given that pigs can carry and transmit the same parasites and diseases as humans, that they're so prominent in the early stages of the game is no coincidence.

　　Then there are the gravitational puzzles, which utilize switches similar to Limbo in order to reverse the gravity of the world, with Inside predominantly using them to alter the direction of water. Finally, the supersonic machine that delivers insanely powerful explosions for no discernible reason in Inside is very similar technology to the rainmaker featured in Limbo, which used similar explosions to incite rainfall in an area. These three prominent similarities - and I'm sure plenty more will be discovered as more people play the game - have led to the suggestion that the factory workers in Inside are reverse engineering the technology featured in Limbo, but I'd wager that Inside instead takes place prior to the events of Limbo, given that the mind control slugs are evidently still in their prototype stage at that point, as evidenced by them latching onto pigs rather than humans.

　　它的设置在同一个宇宙的边缘

　　这是验证很早在游戏的一个主要的理论是，在设置在相同的宇宙边缘，playdead之前的动作。有几个原因，这似乎是真实的，用心灵控制蛞蝓，出现在游戏的入门序列，其中最主要的是。这一次这些蛞蝓不锁上自己的球员，而是在动物特别是他们留下大量死猪尸体猪。现在，他们的猪而不是人类这一次可能是他们被未来的实验对人类本厂制造的喜爱，与猪实际上是现实世界中的人类医学研究的应用。考虑到猪可以携带和传播相同的寄生虫和疾病作为人类，他们是如此突出在游戏的早期阶段是没有巧合。

　　然后有引力的难题，利用为了扭转世界的重力状态类似的开关，里面主要是用它们来改变水的方向。最后，超声波机将在没有任何理由极其强大的爆炸是非常类似的技术来造雨人出现在地狱的边缘，使用类似的爆炸引起一个地区降雨。这三个突出的相似之处，我相信更多的将是更多的人玩游戏-发现导致的建议，在工厂工人的是逆向工程的技术特色在地狱的边缘，但我敢打赌，而不是内部发生到地狱的事件之前，由于精神控制蛞蝓显然仍处于原型阶段，在这一点上，就证明了他们锁定而不是人类的猪。
