A thread risen from the grave yet again...
I really think that if folks would just read from the very beginning of this, they'd see that Chris Blair is dead.
When you're dealing with a completely fictional universe, such as in a videogame, what you see is what you get. The clear message at the end of Prophecy was that he died on the station, and that is what we are supposed to assume and believe until a newer game/book/tv show/movie contradicts that, and explains why he isn't dead.
Wondering if he somehow survived the wreck is for characters within the universe. As third-party observers who are given all relevent information through a God's-eye view, we already know what happened.
He was not shown alive after an event occured which should have caused his death, therefore he is dead.
