how to unlock Abyss in Soul Calibur 3

In Soul Calibur 3 (for those of you who have it) you must understand what a big challenge the final boss, Abyss, is. Well I don't think i speak for myself when i say as soon as i got beaten for the 5th time without even hitting him i wanted to harness that power and play as him. At first i thought the only way to unlock him was to beat him with every single character in the 'Tales of souls' mode. Well, boy was i wrong.
To unlock him it is really quite simple. All you have to do is unlock (therefore defeating) Cervantes, Sphitia, Lizardman, Olcadan, Rock, Yoshimitsu, and successfully complete the Tales of Souls mode. Either that or play 725 battles, I wonder...
