I've noticed pre-release that nobody really knew how to unlock the Flame skin for the Retro lancer. That by itself is not all that weird because we were never told. But now that the game is out, I'm surprised that no one has really even mentioned it. I myself have unlocked it and according to the guide, you get it by playing during the first week. Can anyone confirm if they have unlocked it and if they specifically know the cause of the unlock?
