Waiting for the mission too. Haven't found a relic for ~2 weeks and am not even sure if I've collected all 4. Mission didn't show up on last reset day or armsday.

So what happened for me was after I got all four DVALIN fusion rifle relics, and on a random week this mission called the first firewall came up on earth. Do the mission. The boss drops something for you. It's a puzzle of some sort you can look up on Google or whatever. But from how I see it it didn't actually have a quest in your quest section so it won't put a purple diamond thing above the gunsmith's head until you do the mission. The only way for "The First Firewall" to come up is to wait until a certain day, I don't know which one, and have all 4 DVALIN rifles turned in. After that you're good and can do the rest of the quest on your own time. You could also look up what days the mission shows up

It's on a time lock so the initial cosmodrone mission comes around once a week. But once thats done uou can finish the quest at your leisure

I'm in the same boat, it still hasn't showed up for either. Not sure if you need to be a certain rank with the gunsmith.

Somebody answer the guardian! I need to know to.

Same I still need the fourth dvaalin and I haven't gotten it since the one before which was during the sleepy simluant time

I haven't tried specifically but I heard you can have a friend who has the mission pull you in
