Ranking system guide for BO2

My little brother plays the game and is asking me what it is but i have no idea cuz i dont play

I got that big skull thing but when I go on my 360 its nothing that's changed in zombies this doesn't work

it dosn't let me play please fix this problem if you don't fix this i'm deleting it

I thought this method of calculating rank was proven wrong. I believe the main dev of bo2 zombies put tweets out saying the correct way had something to do with total number of rounds completed compared to total number of downs.

Guys it tells me 110657 kills to level up I don't understand

I typed in kills,downs,arms I think that means tallys and it said i was max rank but on the game im skull and knife with 5 tallys and blue eyes please help

I used it for 5 minutes and language changed to Mexican or something

Ok so today i ranked up to knife with blue eyes but the app says i should still have a skull. It doesnt matter tho bc it still helped me rank up

i did the kill requirements to get the skull with knife but in the game i didnt get it why??? ive been playing for 6 and a half hours just to get the kills and nothing is achived so help me

HELP I don't know what times on the ground means HELP

When I type in all my stuff nothing ever happens its useless

I qustion after u comput what do u do next

im a skull with shot cuns and glowy esy

App works great but what do you mean by "arms"

Love it but what does times on the ground mean

How does it connect to my Xbox please help gt BiggerGuitar5
