Metro The Game on Facebook just posted this, with the quote: Spoiler At least they're still alive and active :lol:
I love that they refer to Artyom's drinking episode in Venice, by saying "You never know where you'll end up"
For a while there, I thought this was a sneak preview of the next metro game, but it seems more like the devs are just having some fun. (I raise you a smiley face).
