people have been saying to install it via the Folding@Home link.... where that link is on the PSN i have no idea, but trying to install it via a larger sized file like Armored Core 4 should work too, am i right? AC4 is 99XMB, the Warhawk beta is 776MB, so that should work i assume... ?
Just got it working through CF3B5's PS3.ProxyServer. I used the Fold@home method. Works great! Fun Game! I can't wait to find some 32 player matches but I'm in taiwan so there aren't really too many servers nearby.
