the campaign is good, with flashbacks. You get to use a vision were your enemies are highlighted red and friends green (which i thought it was cool). you don't get to use many vehicles, and definitely don't like the new SMG gun, i preferred the BR's better. The handgun is perfect against grunts and jackals for head-shooting.
Its a must have, but don't get me wrong i was hoping a little better. Firefight its awesome, especially when you are doing so much killing at one time. You need to get your self a copy now.
