I'm going to say I doubted this guys system at first, so I gave it a try and it works. Be active on a daily and make it to decent rounds 30+ and get alot of kills with few downs and play with friends. Seems the only time I ranked up is when someone else was in the game. 15000 100 downs i got my knife 51000 kills and 150 downs I got my shotguns! Thanks man

For everybody talking mess I was right there with y'all, I reset my stats and put it to a full test and trust me may not be 100% accurate but it's is 90% true, you won't get your rank at the exact number of kills he put. Keep playing and actually do good you will rank up. Be active and play! You are not going to rank up playing and not doing good. Anybody can get 100 kills no downs and quit to keep high stats but that's not doing good play through the whole game!

This does work just be patient.

Nice strategy, I reset my stats and it works. It may not be exact but it's pretty close.

Wow this helped me a lot! Thanks for telling us this.

Now when your saying first second and third mission, are you talking about the campaign missions?

Got my shotguns today. Posted on this last month and finally got my shotguns!

Helpful post

I reset my stats and i found that the two bones to the skull is incorrect. I have a 130 k/d ratio

Kills:2,952
Downs:23

I will let you know if the 5,000 kills works.

I got my skull at 3k kills. your guide is pretty close.

Nice post lots of information!
