Don't most 10th prestige servers reset everything stat wise and just leave you 10/70?
But as for the most epic hacked server I've been into, I got bored and wanted to go for sniper clips on ground war, got into some derail domination..By the time I picked my class I had some "loading x%" across my screen, so it hit 100% and nothing happened.. Ok so now what, I just played the game normally...I got a kill and it said "Intervention extended mags unlocked, then thermal..." I left the game and checked my barracks, I now have --Everything-- unlocked.. It was pretty cool considering I gave up long ago on doing the prestige challenges.
