I'm thinking about getting NX just to get black keys, right now I have 881 NX, which really messes it up for me. I already had one black key and I used it to get the Drugo, but I cant stand the gun, I got like 1 kill in 48hrs with the gun. But everything else is pretty good, nexon for now will keep me as a player, at least untill next month's update, just so I can see what they are coming out with.
