100 Hits / 200 Hits - Damage level 1, cap 1, and use Cable x 3. Build up 3 gauges for BOTH players. Then RB+LB to perform the Cable x 3 team combo, and then perform another team combo ASAP, so that 3 Cables will hit 3 other opponents at the same time, reaching 200+ hits easily.

15 Sec - Damage level 4, cap 5. Easy with any characters.

3 combos - Iron man, QCF PP x 3.

About arcade achievements: set time to 30 and damage level to 1. Wait until Abyss blows himself up for 3 times.

3 BBHOOD? (Vampire Hunter)

3 RYU? (Street Fighter)

100 Hits Achievement

Of course acolyte difficulty does make this game easier to beat, it's still harder than a lot of other games in some ways (for example, Devil May Cry 4). Enemies are much more aggressive, makes this game both more exciting and harder. However, since there are a lot of special techniques this game is not boring at all. Violence is appreciated in this game.

For those who can't even beat the acolyte difficulties, don't say "it's not a good game". Say "uncle".

Got no interests in expert and ace of aces difficulties. A good game like ever, though the CG sucks. And I just happened to notice that "Emmerian" is a parody(?) of "American" :)

Not that good since I don't really play much. But earning CP #4000+ all around the world with GP only 2000+ was really amazing.
