I have a few questions about this game: How long does it usually take to get to 1st and 10th Presitge? Is it healthy to stick to only one kind of specialty in Custom Classes? I'm at lv 18 at no Prestige and I'm not very good yet. Is that normal? Does it help if I listen to music while I play? And if so, what kind? Should I complete Solo Campaign mode before playing Nazi Zombies and on XBOX Live? Should I work towards Achievements or 10th Prestige first? Should I complete Challenges even though I'm not at 10th Prestige? How do you blow up cars? I can't seem to with my Frag and N* thingy Primary Grenades. What takes out a tank better; Satchel Charges or Bazookas? Is it ok if I'm a Sniper to be in one place the whole game taking down people?
