Recently, I joined a game in MW2 on PC and a weird meter bar came up on the screen. Ten seconds later, I was cheerfully notified that all my achievements and prestiges etc had been unlocked for me, which made me very sad, because I've been trying to do them all myself.
So, is there a way to reset all my play statistics so that I can actually try to do them all myself?
Yes. Ensure Steam is running, delete all the files in C:\Program Files (x86)\Steam\userdata\nnnnnnnnn\10190\remote and all the stat files in C:\Program Files (x86)\Steam\steamapps\common\call of duty modern warfare 2\players.
The only way to do this is contacting Steam Account Support and requesting a stats reset.
Now this is not the usual practice, and they are not obliged to do this upon request, but they will help, if you ask friendly. On one occasion I wrote them to reset my achievement progress on Portal because I was stuck getting an achievement, which they did silently.
Again, this is inofficial. Just say the magic word ;)
The only way to get your stats zeroed out is to start a whole new character with a new gamertag.
For xbox players with the same question about resetting your stats to get a better K/D or accuracy stat: There is no way to reset your achievements or stats. However, when you enter Prestige modes, after reaching Level 70 (Prestige 0) you completely hard boot your character. You lose all of your perks, killstreaks, deathstreaks, guns, everything. You begin earning them again as if you just started playing Multiplayer, except you already have stats. Also, once you are one of the 10 levels of prestige, you have a more covetted icon next to your name.
