"If a player enters Prestige Mode in Modern Warfare 2, every unlocked weapon, killstreak, perk and challenge will be reset. (Prestige challenges, which are unlocked at 1st prestige, are not reset and will be collective across all prestiges except "Heads up!", "Knife Veteran" and ones below Knife Veteran.) "

Now, if you're talking about the prestige challenge, no it does not. I believe it states that when you prestige.

Does it take a friggin admin for routine crap?
