The much-hyped title launched in June and since then, 'Tekken 7' has moved 2.3 million copies across all platforms, according to game director Katsuhiro Harada.

Reflecting on the success, Katsuhiro wrote on Twitter: "Over 2 million now (2017 June to September). (sic)"

By comparison, 'Tekken 6' sold 1.8 million copies in its first seven months on the market, suggesting that the most recent title is performing excellently.

What's more, 'Tekken 7' has also been well received by critics and fans following its launch earlier this year.

Meanwhile, Katsuhiro revealed earlier in 2017 that he wants to make it possible for PlayStation and Xbox users to play multiplayer games together.

Katsuhiro said he supports the idea of the two consoles using their online systems, PlayStation Network and Xbox Live, to allow users of either console to cross-play with users of the rival platform.

But he also admitted: "Since 'Tekken' has three platforms, to do [cross-play] is much more difficult because fighting games are peer-to-peer, which means you connected directly to your opponent.

"That means all the security protocols regarding PSN or Xbox Live, the user IDs and such, is quite difficult to match that - not technologically."
