D3 Publisher will have three playable titles at Tokyo Game Show later this month. On Vita, there is Earth Defense Force Portable V2, port of Earth Defense Force 2 for PS2 with the Air Raider as a playable character. Onechanbara Z2: Chaos, a new zombie slasher game with a four player mode, and Earth Defense Force 4.1: The Shadow of New Despair, which was announced during Sony’s pre-TGS presentation will be at their booth too.
While we haven’t heard too much from D3 Publisher, they have localized all of the Earth Defense Force games since Earth Defense Force 2017 for Xbox 360. Earth Defense Force 4 was released as Earth Defense Force 2025 earlier this year, but so far D3 Publisher USA has not said anything about the PlayStation 4 version.
