Level-5 published a brand new trailer for Megaton Musashi ahead of Jump Festa 2020. The trailer goes over what we know about the game's story. It's set in the future where the earth was colonized by bad aliens called the Dractor. The survivors fled to underground shelters, and fight against the aliens using "Megaton-Class" mechas, hence the full name of the game in Japanese: Megaton-Class Musashi.

The trailer mentions Megaton Musashi is a "Cooperative Robot Action RPG". It's currently unclear whether if the game can also be played solo with allies controlled by the AI or not. The trailer mentions online co-op battles against giant Dractor enemies and mecha customization.

The trailer also introduced us to three mecha in the game and their pilots:

It's important to note the seiyuu for Yamato, Teru, and Ryuugo changed over time. Back when the game was first revealed in 2016, they were respectively voiced by Mazakazu Morita, Miyu Irino, and Tatsuhisa Suzuki. These three are highly popular and costly seiyuu, but the new ones are extremely popular as well, so it's just a guess, but it shouldn't be a money problem. Instead, the change is probably a consequence of the various delays and development changes Megaton Musashi went through. Personally speaking, while I liked the old cast too, I'm pretty happy with the new cast, seeing Toshiki Masuda, Soma Saito, and Shunsuke Takeuchi all voice characters in the Pretty Rhythm/King of Prism franchise, one of my favorite anime.

The game's overall atmosphere, from the illustration of the characters, or even the trailer's video editing itself, feels much more aggressive overall compared to what we've seen in the past:

For comparison's sake, here's above the first Megaton Musashi visuals we got in 2016. Meanwhile, the new look revealed in the new trailer gives off a similar vibe to Hiroyuki Imaishi and Studio Trigger related anime, such as Guren Lagann, Kill la Kill, or the studio's greatest masterpiece, Turning Girls. You can also see how the game interface changed. The space suits and how each mecha is piloted by three pilots seem to be ditched ideas.

Megaton Musashi was first announced in July 2016 and was supposed to launch in 2017. However, similarly to Yo-kai Watch 4 or the next Inazuma Eleven game, it was delayed many, many times. Level-5 president Akihiro Hino explained how the company is changing to avoid such delays from occurring again.

Megaton Musashi is a joint project between Level-5 and Weekly Shonen Jump. Just like other Level-5 franchises, Megaton Musashi is also supposed to be a multi media franchise with an anime adaptation. However, we never heard about the anime version since the pilot released in July 2016.

Megaton Musashi will be featured at Jump Festa 2020, on December 21-22. A demo of the Switch version of the game will be playable at Level-5's booth. It'll be the first time ever the game is playable. A giant balloon of the Musashi mecha will be on the stand, and trying out the demo will net you a Musashi mini cardboard stand.

Megaton Class Musashi is coming to PlayStation 4, Nintendo Switch, iOS, and Android. The game has no release date estimate.
