(level ##)=The level at which the challenge is unlocked

(lvl??)=The level the challenge is unlocked is still unconfirmed

Weapon Specific Titles
Some titles are unlocked by completing challenges with specific weapons. It is possible to unlock five separate titles for a weapon, but not every weapon will have all five.

'''Below are examples of the five types of weapon specific titles along with the weapons that are eligible for each type. (Note: Headshots with Launchers aren't counted, so Multikills are required instead).' Italics show which challenge is needed. You must prestige to unlock the latter four challenges (Veteran and Master)''.

Prestige Specific Titles
Some titles are only awarded after a player has committed to prestige. Below are the non-weapon specific titles awarded for completing certain challenges or attaining certain levels after starting Prestige mode.

For the Killstreak Challenges, 250 kills are needed for the Silver title using that killstreak, and 1000 are needed for the Gold title using that killstreak.
