Tekken 5: Dark Resurrection is to get an online mode, so you can challenge anyone who has the game (and a PS3) from across the world. The update which allows online play will be available as a download on the Playstation Network for those who already have the game, or in a pack with the full game for newcomers.
Various matchmaking options will be available, along with a ranking system and voice chat, and once purchased the game will be free to play online. This has caused some fans to complain about being charged for online play even though it will be a one off payment and not a subscription.
No date has yet been announced for the release of the update. (From NeoWin.net.)
