User blog:Gracchus Mccarthe/You can get a black box by ranking up.

I recently ranked up (after losing a MP mission; I barely had any XP left to go), and the notice showed that I received a Titanium strongbox.

After exiting out of that, I didn't have a box to open (since we lost the mission). After a few seconds, it showed the black box screen. I didn't have a black box before this mission.

So yeah. Crazy, right? Also, this is proof that black boxes are just black versions of regular boxes.
