Soul Blade� where the player must defeat enemies under certain conditions in order to unlock extra weapons for the characters. It is similar to Weapon Master� mode on Soul Calibur 2, except the player cannot buy weapons. Many of the quests involve defeating enemies within a brief period of time, using air combos to defeat them, or beat them when you start the match on low life.
All of the characters begin with one weapon, that has standard stats. Nearly every episode gives the player a new weapon. The ultimate weapons cannot be found until the player has completed all episodes at least once, and finding them is very tricky. The Edge Master Walkthroughs can help you.
