Most likely the actual online mode for MHP3rdHD will be Adhoc Party itself. I know it sounds weird but that is pretty much the only way to pull it off. Playing an individual game and AHP at the same time (given both are on PS3) is impossible under normal circumstances. By actually linking the 2 together however, as two halves making 1 whole, it is theoretically possible I guess.
