Also, Theirs this really nifty program called "PSE" or, "PlayerStats Editor." It lets you modify the playerstats.txt file that you import using Easy Account Manager. And the best part about it, is that you can edit everything, easily, Played time, weapon unlocks etc. Since I can't give a link to the site, I'll give you these 2 links.
Easy Account Manager - Just click whatever link pops up.
Let me google that for you
