MUTAN Inc.(CEO: Hiroyuki Watanabe) has updated “Goonya Monster” for Steam(R), Nintendo Switch TM and PlayStation(R)5 on February 1, 2023 at 00:00(JST).

We are pleased to announce the start of a new season, Episode 2, featuring a new character, Anemone (Character Voice: Akari Kito), as well as the addition of new stages and monsters. We are also pleased to announce the release of a roadmap outlining our future update policy.

This title is a “3vs1 asymmetrical party game” played by three “busters” and one “monster”. The theme song is by “FAKE TYPE. feat. super students” and the characters are designed by the popular illustrator “Terada Tera”.

This season, Episode 2 opens with new elements

Two new monsters and one map will be implemented into this update.

Monster: Baby

Skill: Gyan Crying

Screams loudly to paralyze nearby busters!

Monster: Balloon

Skill: Balloon Levitation

Floats on a large balloon and drops bombs from the sky!

Bouncing on a jump platform, moving at high speed on a conveyor belt, and other gimmicks that expand the ways to fight, the “Toy Factory” is full of new features.

In addition, a new character, “Anemone,” will appear in the implemented storyline.

Anemone” is a mysterious scientist (a mad scientist) who is human but manipulates the undead and antagonizes Buster. She is usually calm, but when it comes to her research, she shows her crazy side. She was working on a special research project that was halted due to opposition from those around her… Her purpose will be told in the story that will be released by playing “Episode Match” in the future.

A Promotion Video introducing the contents of the update is also available.
