10 Biggest Unsolved Mysteries In Video Games

Anyone who has played a Fallout title knows about the Mysterious Stranger. An unlockable perk that players can pick up, the Mysterious Stranger will show up every so often in conflict to deliver critical shots and finish off enemies.

And up until the release of Fallout 4, that was about that for all we knew about this shady character. But for the 2015 title, Bethesda intentionally worked in some added depth to the man that has left players pondering over the true nature of this assassin.

Nick Valentine is an android and private investigator players can have as a companion as they travel across the wastelands. If the Mysterious Stranger shows up whilst Nick is around, the PI will react with great shock and curse how the man was able to "slip through their fingers".

Nick even has his own case file built against the Stranger that players can read in Diamond City, drawing his own theories on who and what his identity may be. Sadly for players, it seems this android is in the dark as much as they are when it comes to any concrete answers.
