Tekken 7. "BETA TESTING NOW> New Rendering Camera System "Both players can play on LEFT SIDE (or RIGHT SIDE) for TEKKEN7," Harada tweeted.
Initially this idea seems confusing, but the image Harada included - which can be seen, in part, above - makes the new feature clear. Harada's team has linked two Tekken 7 arcade cabinets and programmed the game to rendered mirrored images centering on the two fighters for each display. The effect is that both players are fighting from the same side in the same, real-time match with data being shared between the two cabinets, hopefully with very little lag.
However, the utility of this feature is questionable, especially for anyone outside of Japan. Players who prefer to fight from one side or the other may embrace the option (assuming it makes its way successfully through beta testing), but as the system requires an elaborate grafting of two undoubtedly pricey Tekken 7 arcade machines it will only appear in larger, well-funded arcades. Given the collapse of the arcade market in the West, this effectively renders the mirrored system exclusive to Japan and a few locations scattered throughout North America that might buy the system purely for its novelty.
