can i get LIVE from my pc for COD4??

to make a long story short...

i had COD4 for 360 and loved it. my live ran out....then my 360 got those damn three rings

so....i thought about getting COD4 for PC.

but, im not so much into the campaign, just i love the multiplayer.

can i subscribe to live thru the pc version of the game or can i only play with people using it on pc??

also, is it the same as the xbox version or any better/worse??

thanks.

ah thanks man.

thats just what i wanted to hear.

kinda wish that there was prestige but w.e ill learn to cope with it.

also.. being that you still play im assuming that the servers are very active...unlike many shooters i find in the stores for sale..

but yeah cool thanks man.
