A few details on Namco's big arcade sequel.
First up, one tiny bit on the location test. In addition to the hint at the timing, the Tekken 6 staff revealed to Arcadia that the location test version will include playable versions of the two new characters that were shown at AOU, Leo and Zafina.
It seems that the game will have more than just those two additions to its roster, though. The staff wouldn't give the final character count but stated that they don't want to include just one or two characters, and they don't want to drop the character count from Dark Resurrection.
The Arcadia article also touched upon something that was hinted at in the AOU footage: interactive backgrounds. The backgrounds will change to reflect the passage of time. They'll also be greatly affected by player actions.
