1. What exactly does this option reset?
Selecting the Stats Reset option in Call of Duty: Ghosts will reset your Prestige, Levels, and Squad Points, as well as your core Leaderboards stats. Game mode specific leaderboards, reticles, patches, gear, and camo unlocks will stay the same. The Stats Reset option is only available to players who have achieved Max Prestige.

2. Will other players be able to tell that I reset my stats?
There is no indication that someone has specifically reset their stats. However, unlocked patches aren't reset. So if a player who has reset stats is using a patch that would normally be locked at the player's current rank, it's obvious that the player has completed a stats reset. Also, the counter that keeps track of time played will not reset when using the Stats Reset option.

3. Will I be able to restore my stats after using this option?
No, all stats resets are final. Once a stats reset has occurred, there is no way to recover anything that has been reset.

4. Does the Stats Reset option affect Extinction stats?
No, stats resets only affect standard Multiplayer stats. Extinction stats are unaffected.
