Everrything resets except for titles and emblems. So yes.
No. You have to prestige.
All your guns, attachments, equipment, perks, level, classes, and challenges reset.
You can obtain new titles and emblems but that is all, everything else such as weapons and challenges are reset.
no everything is reset except titles and emblems
When you enter prestige mode, you reset your rank, you'll have to earn everything from weapons to perks to challenges. Titles and emblems are not reset though so you can keep them. You get a new challenge group called "Prestige" which can earn you some cool titles
No
Complete the AC-130 challenge by using the AC-130 25 times, you must unlock the killstreak challenges and must not prestige before completing it since all challenges are reset after you prestige. Hope this helps :)
You lose all the weapons you've achieved and you have to earn them back. You unlock new challenges, embles, titles, and more Custom classes. The highest rank Prestige you can get to is 10. After entering prestige mode, you are reset to level 1 in 1st prestige with a different emblem than the default one.
Unlock the killstreak challenges and get 10 nukes while in the current prestige, if you prestige then all challenges are reset meaning you will have to unlock and do the challenge again. Hope this helps :)
Yes, everything in the Barracks resets besides your title, emblem, and clan tag. But if it's your first time to prestige, then you get the Challenge category "Prestige." Plus, you get two new Challenges for every weapon except the Riot Shield. Once you finish these challenges, you unlock a new title and emblem.
If a player enters Prestige Mode, every unlocked weapon, killstreaks, perks and challenges will be reset.
theoretically you are capable of unlocking all titles minus about 3 titles per weapon (both primary and secondary). the reason for this is that you cannot start working on the 'Veteran' and 'Master' challenges until you have prestiged. In addition to these gun specific challenges there is also an extra section added to the challenges in the barracks under the title prestige. The PRESTIGE challenges which are mostly killstreak kills and stealth,stun related challenges for which there are 15 challenges. MOST IMPORTANTLY, is the fact that master, veteran and prestige challenges are highlighted in green indicating that they will not reset should you prestige further.
