New Visuals and Characters for “Goonya Monster” Drawn by Tera Terada – And New Character “Slug” Voiced by Mel Kishida

MUTAN Inc. (CEO: Hiroyuki Watanabe) is excited to announce the release of new visuals and characters drawn by Tera Terada for the asymmetrical party action game “Goonya Monster”. The visuals showcase a slightly darker side of the game and are centered around the mysterious scientist “Anemone” who appeared in Episode 2 (which has already been released).

Anemone will also be a playable character (Buster) in the DLC for Episode 3, set to begin on May 1st. Three new characters featuring new voice actors, such as Mel Kishida, will also be introduced.

What is Goonya Monster?

Goonya Monster is an asymmetrical party game in which three players are “busters” and one is the “monster”. The busters fight using their unique weapons, while the monster fights using powerful skills, with both sides aiming to achieve their own victory conditions. The theme song is by “FAKE TYPE. feat. Super Student”, and the characters are designed by popular illustrator Terada Tera.

New Character Introduction

The characters will be brought to life by experienced voice actors who have worked on numerous productions. You can choose your favorite voice not only during battles, but also on the menu screen and in system messages.
