Okay so on my old account, Killbook, I had no chance of even getting the knife and skull due to how horrible I was when it first came out because I was helping my friends get persistant quick revive and so I made a new account called ZZ killbook. It took me two weeks. I made the account two weeks ago and since I have a family membership pack, I added it to it. I then went onto aiming for a particular goal. I would play MOTD everyday for a couple of hours which is about one game or more for me. I started off as a bone and as you know, no one likes bones so, whenever I got in a lobby, I would have to inform everyone that it was a new account for them to play with me. My first game I went 2000+ and 2. Then, the rest of my games were like that. I got ranked in up one game, and ranked up another time in 3 games and ranked up another time in about 7 games. My K/D always stayed above 200 and never went down since I reached the skull. I got my blue eyes fast and when I got my knife, I only played 3 games and I got my shotguns in the middle of a game when some guy lagged out. I was astonished and overjoyed by the new rank.
If you have over 1000 downs and stuff, I highly recommend getting over 1000 kills on EVERY game and getting under 10 downs per game. You'll be a shotgun rank in a week or two. Playing solo isn't going to cut it either, you need to be a team player. If someone gets down, risk your life (If you're good enough not to down) to go revive them. I've done it more than enough times and have survived every time. Aim for 1000 - 0 ratio per game and keep going up. If you get down, go 1100 - 1 and so on. Match your ratio by 1000 kills per down. If you can't do that, do it by 100 kills per down. If you can't do that, you won't be able to obtain shotguns.
Next, play things like die rise or tranzit or mob of the dead. I highly recommend mob of the dead because it's fun and exciting and it's easy to handle. I've even made some videos on places to train. Here are videos of where to train and how to train in them. WARNING: These places are very ACTIVE in spawn rate and it is advised you are a good zombie player to maintain these places. Recommended weapons are the Golden Spork, Hell's Redemmer, BlunderGat, PaP gun, Shock Cherry, Juggernaught, Double Tap II, Speed Cola, Zombie Sheild. All this should be done and aquired by round 19 (and to make it a challenge, do it all without dying). By round 20 +, these places will be very active if you're by yourself.

I love the map mob of the dead so I go out my way to find things to make it more fun. I don't camp in one spot every game, I go search for new spots to camp and make it a bit more hard even with all the perks and etc to where it's going to be insane with none of that. You should do the same thing too. If someone is one of your favorite spots, find somewhere else. Like I said, mob of the dead is MY favorite map and it's where I've been to get shotguns. If you don't like it or don't have it, you don't need to follow this guide. It's just an example. Do what I do on maps like tranzit or die rise or nuketown. Make the map your's. Have it where you can walk ANYWHERE on the map and camp there and not die.
