You have to get the special addition pack for prestige mode haven`t you?
and also to get the Petrol car thingy and the crossbow?
Nope. The prestige edition is just a BO with added things, you can still prestige in a normal BO.
There was MW2 Prestige Edition as well with Nightvisions which i didn't bought but i could still prestige. >.>
And btw, are Hardened and Prestige Editions of the game only for consoles? I was visiting some site with pre-orders and there was only normal version for PC.
i know really much about this game because of a web site il post it later
But whats confirmed is that its not 10 prestiges its more or less and normally for a noob they have checked that it takes like 24-32 hours to rank to lvl 50 (and thats the last level) and for a really good player it would take 12-20 hours to rank up to lvl 50
