Phantasy Star Portable 2 Best way to Experience Co-op

[TkSilver]

So Story mode does unlock more multiplayer missions. You can power level the lower level character by just doing a few multiplayer missions that are low level for the higher level plyer but missions the lower level one could not complete on his own to gain exp faster. But no most of Co-op is locked behind clearing at least a decent portion of the story mode.
