Tekken 8 Gameplay

Directed by Katsuhiro Harada, Tekken 8 places a heavy emphasis on aggressive gameplay. Players are rewarded for attacking rather than defending. The game introduces a new feature called the “Heat” system, which can cause chip damage, additional moves, and change character abilities, such as heavy defense breaks.

The heat state timer is stopped during active movement, and defending against certain attacks causes chip damage, boosting health bar regeneration through offensive play.

The returning Rage system has been revamped with “Heat Smash”. The obsolete “Spiral” attribute has been replaced with “Tornado”, expanding the juggling combo. TEKKEN 8 aims to create a cinematic feel with stage destruction, new character models, and the power of Unreal Engine 5. Online modes include “Arcade Missions” with customizable avatars through “Battle Money”.

Tekken 8 Development

The development journey of Tekken 8 began with a trailer at EVO 2022 and an official announcement during Sony’s State of Play on September 13, 2022. The game will be released on PlayStation 5, Windows (via Steam), and Xbox Series X/S, continuing the saga of Kazuya and Jin from Tekken 7.

After the 2022 Tekken World Cup Finals, Arika oversaw continued development work, including rolling back the network code. Bandai Namco conducted closed network tests in July and October 2023 to fine-tune aspects such as balance and matchmaking.

The demo was released in December 2023 and provided a taste of the game, including the story mode, arcade missions, super ghost battles, versus mode, and the gallery.
