Depending on the COD, it changes the amount of levels they earned.
COD4: 55 levels
COD5 WAW: 65 levels
COD MW2: 70 levels
Each prestige has a certain amount of levels needed before going into the next prestige. In MW2 its 70 levels, then prestige, then 70 more levels. Since you need to reach the highest rank before prestige 1 there is actually
COD4: 555 levels total as a tenth prestige.
COD5 WAW: 715 levels total as a tenth prestige.
COD MW2: 770 levels total as a tenth prestige.
Lots and lots of games played :)
The only thing going to tenth prestige does is get you more titles and emblems, bragging rights, and prestige tokens. If you are not interested in either of these, there is really no point.
To tenth prestige you have to prestige ten times
Prestige 10 times funnily enough
yes
To reset your stats you must be Tenth Prestige Level 80 and have a prestige token.
Yes. Everybody does really.
no
Keep playing until you get 10th prestige
There are no unlock differences between hacking and not. But you will get a prestige title and the acomplishment of being a legitimate 10th prestige.
No don't be a living downy!!
Yes I think so
Not besides bragging rights.
