tip: if you need bloodthirsty medals, you get them easier when you play ground war, many players are init so more chances to get them

More sneaky players spawning behind you though

every gun diamond just need to max them now

wow james how much do you play it lol

me and bro share the xbox but generally 6 hours a day to ease my boredom

My tip is play it safe and do not be eager to rush the enemy spawn especially from 3+ kills. Also keep moving so your not an easy target, oh and play Hardcore for easy kills

Well i got master prestige and finally got all diamond guns (took hell of alot of deaths just trying to get headshots ) and yesterday after 5 years my ps3 decided to get that yellow light of death thing . Not sure if to get another or wait till end of the year/beginning of next year for the PS4

dgen how do you get your headshots well best method

Was dam hard getting 1 bloodthirsty for the xbow, 5 out 6 rounds had to kill, got there in the end though
