Traditionally, the A and B buttons have mapped to horizontal and vertical slices, respectively. In true waggle fashion, Namco has felt fit to physically map these actions to the Wiimote. We're wary; the recognition will probably be fine, but seeing as how at least two-thirds of all moves in previous Soul Calibur titles involved the use of one (or both? What the heck?) of these actions, this might wear out its welcome very, very quickly. Also, the nunchuck is shaken for "evasion," whatever that means (guard impact?).
The title will allow for tag-teaming against a boss, as a second player can join in for cooperative fun. There's traps and obstacles and all that lovely goodness as well; for some more minor details, check out the in-depth IGN report. With the announcement of the true Soul Calibur 4 for the PS3 and 360 yesterday, are you guys still excited for this?
