Which main Tekken game first had home releases on Xbox 360 and PlayStation 3? Tekken 6 was the first.
Tekken 6 debuted in Japanese arcades in November 2007, running on Namco’s System 357 arcade board, which was based on PlayStation 3 hardware. Its home edition arrived in October 2009 for both PlayStation 3 and Xbox 360. That Xbox release was a major series milestone: earlier main Tekken games had been tied primarily to Sony platforms.
The console version was based on the expanded arcade update Tekken 6: Bloodline Rebellion, although the home release kept the simpler Tekken 6 title. It added online versus play and Scenario Campaign, a beat-’em-up adventure starring Lars Alexandersson and Alisa Bosconovitch. A PlayStation Portable version followed soon afterward.
A common mix-up is Tekken Tag Tournament 2, which also appeared on Xbox 360 and PlayStation 3. However, it is a spin-off rather than a main numbered installment. Tekken 6 is therefore the canonical answer for the first main-series release on both systems.
