"Nuklearni-okurka" said:Soul Calibur is the second game in the Soul series by Namco (first game was Soul Edge). All future games in the series got the Soul Calibur moniker, so Soul Calibur IV is actually the fifth game in the series. The games are fighting games whose plot revolves around two legendary swords (Soul Edge and Soul Calibur, representing Evil and Good, respectively). The games take place sometime in the 1600's, so as you can imagine, the appearance of Darth Vader and Yoda is somewhat surprising.
I'll get flamed for this but... Wtf is Soul Calibur?
