i dont know ;),i played the arade mode today and beat the game with venom,morrigan,and mega man.first time against abyss i made it to his final form with 2 characters but he got me when he just had like maybe 2 or 3 hits left.beat his ass the next time.the analog stick is way more responsive than the d pad,it just takes some time to get used to it.
it was weird that there was no ending though.i did beat it on easy,but still.its as challenging as the settings id have on ps1 fighting games from capcom.i think with no individual endings ill be less inclined to beat it with every character like i have for any fighting game ive had(other than def jam fight for ny).
