I failed 12 attempts at survival mode as an interloper, but still wanted to try in some more because that blizzard is hot. Kidding I gave up at 15 and tried playing as a stalker instead.. also failed. I then tried Wintermute (which I haven't finished yet) and I'M EXTREMELY happy with how everything is unfolding. Oh and yes, I killed someone... he had it coming. It may or may not bring me bad luck but it's definitely nothing Mackenzie can't stand up against. Recommended!
