It isn't rigged. What happens is that it's like bingo. You buy gray hisec keys for the 5 shot cases. You open the cases and get a random number on your board. When you get 5 in a row, you can claim a reward like a camper's backpack, respawn tokens, NX guns, etc. You sell back the NX guns for profit, and when you complete it, you gain profit. IMO, it's not rigged, because I did it all on gray keys. If this helped, press thanks.
