Top two you can find by using the "
DNF Episode Quests" guide in unplayed's sig. The bottem one is event, dunno what to do. The 3 above that are time based. Beat giant Tau in Xmins, beat next one (forgot the name) in Xmin and beat thunder boss in Xmins. Above that is a party thing, ive never done it cause i couldnt be bothered looking for a party. The other 3 above those are collect X amounts of X from different maps. ウエストコーストのロリアン, i THINK is Giant tau.
