King of Fighters XII Clans Appears to be PS3 Only
It looks like the clan functionality for King of Fighters XII will be a PlayStation 3 only feature. Siliconera has done a bit of comparison of the Xbox 360 and PS3 versions of the game. The have noted omissions to the online modes and included a screen capture for evidence.
Also interesting is King of Fighters XII has a different set of options in the online menu depending on the console. On the PlayStation 3 players can pick “Clan” which is not found in the Xbox 360 menu. Instead the menu has an option for a “ranked match.” Clan mode is a bulletin board (BBS) like system where players can post messages and issue challenges.
