With the help of videos on YouTube and stats on this wiki, I have created the ultimate custom loadout for close-to-medium-range combat. I call it the "CQC Master" class. If anyone wants to give it a go, here it is:
Note: brackets around something means this is optional.
Primary weapon: UMP45 w/ ACOG scope and Extended Mags
Secondary weapon: G18 w/ FMJ and Extended Mags
Special grenade: Stun x2
Perk 1: Bling Pro
Perk 2: Stopping Power (Pro)
Perk 3: SitRep Pro
For those of you who play multiplayer, give this class a go if you know there'll be a lot of close-to-medium range fighting. Leave me a comment to let me know how it went. Satisfaction guaranteed!
