It is kind of like that elite web thing, except it actually works.
This app does NOT integrate with your character's stats though. It is a utility for viewing weapons, weapon proficiencies, attachments, multiplayer maps for all modes, assault kill chains, support kill chains, specialist kill chains, perks, death streaks, includes a kill/death calculator, and now includes titles and emblems. Everything is organized to be quick, easy, and intuitive to use.
Is there something else you need? Just send us a suggestion through the app.
