For all of you that don't know, the first firewall is the mission that kicks of the quest for sleeper simulant, after you get your 4 dvalins. It is similar to the mission for the black spindal and is only available for a day. Of course, if your reading this you probably already know what it is. But my question is when is it coming back. And for those of you that have completed it, is this mission hard? What are your thoughts on this mission?
