Namco Bandai Games Europe has announced that development is now complete on Tekken 6 for PSP, with the handheld title set to hit retailers across Europe on December 11, 2009.

In addition to containing all 18 battle stages and 40 playable characters found in the home console version of Tekken 6, the PSP game also supports ad-hoc multiplayer versus battles fought across four additional stages.

Game modes include Arcade, Story, Ghost, Challenge and Practice, while the ad-hoc wi-fi features include the ability to send and receive ghost data allowing fights against opponents' characters even when not connected with them.

We've fired off an email to Namco Bandai Europe to find out if the game will support adhocParty using a PS3.
