When originally released in 2003, Heihachi and Spawn were exclusive characters for the PS2 and Xbox respectively. However, the upcoming HD re-release of the best entry of the franchise will do away with exclusive rights and allow players on PS3 and 360 to enjoy both fighters.
Heihachi, the mental old dad from Tekken is something of a hard sell in SC seeing as he's the only unarmed character, but anyone daring to rock that hair and start on people with swords is going to be worth a shot. Comic book star (of many years ago) Spawn, seems much more at home with a tasty-looking axe to cleave opponents with. Not so sure about the outfit. Voldo might take him on a date though.
