I want to know if you prestige, do you get to keep the unlocked tokens you have gained?
If you are referring to the unlock tokens you use to unlock guns and perks, then no, they do not persist across prestiges. It is to note that even at max level, there are not enough unlock tokens to unlock every single piece of gear (Perks, Wildcards, Guns, & Equipment.) The exception for this is reaching Prestige Master, when all gear will unlock and you will have access to every item. When you prestige you do get a single 'Prestige unlock' which you can use to do one of 3 things
- Fresh Start: Completely reset all stats and start at level 1
- Unlock Token Reset: Refund all spent unlock tokens, to unlock different gear
- Perma Unlock: Remove an item's level minimum so that on further prestiges you do not have to level up to unlock the item. (Still must be level 4 to unlock Create-A-Class)
In Black Ops 2, when you prestige, all the guns/perks are locked back. When you reach level 4 and access the "create a class", they're locked (except the ones available at level 4). When you reach the level where it's available, it will automatically unlock and go back to the level it was before you prestiged, so you don't lose the progression, and the equipments you previously unlocked are available.
The only way to have the item unlocked at level 4 is by using a prestige token to permanently unlock the gun/perk (create a class, choose the weapon/perk/equipment and press RB/R1 on XBOX/PS3). It will then be available as soon as you reach level 4 on each prestige. If the gun reaches its max level, you can prestige that gun and send it back to level 1 (main reason is so you can re-earn XP from attachments challenges).
I hope it's clear ! For those of you who may know better, if I'm wrong in some way or if I missed something, please tell me !
