Like most Nintendo 3DS games, Tecmo Koei’s Dead or Alive: Dimensions is compatible with the system’s Cross Pass (Tag mode) functionality, whereby 3DS systems can communicate with each other while in sleep mode.
While Super Street Fighter IV 3D Edition uses Cross Pass for automated figurine battles using custom stats assigned by the player, Dimensions goes a different route, according to Nintendo president, Satoru Iwata.
Iwata revealed at a recent investor presentation that Dead or Alive: Dimensions uses the 3DS’ Cross Pass functionality to exchange character parameters and player patterns between different 3DS systems. The game’s single player mode can then use these player patterns against you.
Similarly, in Konami’s Pro Evolution Soccer 2011 3D, you’ll be able to exchange players and formations that you’ve registered. These can then be used for playing some sort of a simulation game.
