He might have suffocated or got attacked by the dark ones who knows? he might still be alive but could not come back because he was trapped or something...What do you lot think? :derp:
Well, you might wanna get the books. You never know when Metro 2034 will be released in english But I'll just write the basics here. Spoiler He survived the Dark Ones, but they made him realize the beast he was. He then went to help Sevastopolskaya.
Yes, but I would add a bit more onto that. Spoiler He is left extremely traumatized and finds it hard to express human emotions or empathy after what has happened. Everything is explained in Metro 2034, prince. I highly recommend the book if you know any of the languages that it has been translated into.
If you only read in English, there's a guy on Youtube that has a decent translation from German. In fact, I think someone has posted the link to his website on the forums some where. Forgot to mention that this is for Metro 2034 ^ The English version of Metro 2033 can be found online on websites like Amazon.
I found the link for you if you're struggling to find it. http://metro2033artjom.webs.com/metro2034download.htm
