Don't think its available for public download as it's still being conducted as a closed beta phase. Whether they're gonna conduct an open beta one is still up to EA.  I've been playing it quite sometime and i say it's pretty mediocre and like most people would say, it's just BFBCII except with smaller maps. My experience with the closed beta is like i said earlier a very mediocre one. After having a bomb with the mp experience in the MW series, this really feels nothing new however since it's still a closed beta, i'll reserve my further judgement  of the game when it's at a much more polished stage.

Relax bro, we can play the multiplayer DEMO! Beta is bad for your ps3..hehe

ya... at the meantime you already started playing COD black ops and totally forget bout MOH...
