if you really just want to rape people and piss them off:
ump silenced
aa12
marathon pro
leightweight pro
ninja pro
semtex

didnt realize thread title hardcore, i dont play hardcore....

my usual class:
tar silenced
m1014
marathon
stopping power
ninja
semtex

all time favorite:
uzi silenced
spas 12
marathon
stopping power
ninja
semtex

(stun grenades all around because you can throw them faster)

Depends on your playstyle, I never play hardcore but I have a lot of friends that do and they usually have marathon lightweight ninja on an assault riffle or SMG silenced with semtex and stuns. But if you wanna sit back and play more defensive than you could use an LFG with grip SoH, Hardline/Cold blooded, Ninja/sitrep with claymore and stuns, or an assault riffle bling RDS and silence, Hardline/Coldblooded, ninja/sitrep with semtex/claymore with stuns.

Why use Stopping Power on hardcore?

UMP Silcenced
PP2000 RDS
Marathon
Cold Blooded
Ninja
Claymore
Stun

You should use Extended Mags if you have it, the PP2000's iron sights are awesome.

Ew, It needs RDS. & It has no recoil

i don't play hardcore.... i play regular because its harder than hardcore. plus i got sick of running into team killers

I use:
M4/Ak noobtube
thumper
slight of hand
cold blooded/hardline
ninja
win
Incase you didn't know... I just spawntube my ass off...

Without a doubt, FAL is a 1 shot kill in hardcore (With stopping power) and what could be better than a pinpoint accurate 1 shot kill assault rifle ?

opinions ?
