Stellar Blade developer Shift Up has acquired 100% of Tokyo-based Unbound, the studio Resident Evil creator Shinji Mikami quietly founded in 2023 after leaving Tango Gameworks.

The Korean company announced the share purchase on Wednesday. Financial terms were not disclosed. As part of the deal, Shift Up will publish all of Unbound's future titles and back the studio with development resources.

Who is Unbound?

Mikami established the studio after departing Tango Gameworks, the ZeniMax-owned developer behind Ghostwire: Tokyo and Hi-Fi Rush. His credits at Capcom include directing the original Resident Evil, its 2002 GameCube remake, and Resident Evil 4.

According to a website Unbound published last year, the studio employs around 50 people working on an original AAA IP for consoles and PC.

What changes for the two studios?

Shift Up said the partnership formed after Mikami and Shift Up CEO Hyung Tae Kim found they shared a similar vision for game creation. The announcement described Unbound's operating model in concrete terms:

• Parallel development tracks: smaller experimental titles run alongside a large-scale flagship project.
• Neither ambition nor risk-taking gets sacrificed to the other, according to the company.
• Shift Up takes over publishing duties and supplies development support going forward.

"What draws these two together isn't geography or market logic. It's a shared conviction that strong creative direction and high-quality execution go hand in hand," the announcement reads.

A teaser video accompanying the acquisition appears to show the first glimpse of Mikami's next game, featuring a multi-winged monster towering over a destroyed city.

What did the executives say?

Mikami framed the deal as a way to protect creative focus. "I am very pleased to be partnering with Shift Up CEO Hyung-Tae Kim and all the employees. I sense strong synergy with CEO Kim, who is also an active creator, and I believe this is an ideal partnership that allows us to focus on creativity," he said in a statement.

"We will do our best to create fun games so that both companies, working as one, can meet our fans' expectations."

Kim positioned the acquisition as a strategic play for Scale: "I find it deeply meaningful to join forces with Unbound, which brings together a world-class development team led by CEO Shinji Mikami. This acquisition will serve as an opportunity to deliver the best gaming experience to users worldwide and further solidify Shift UP's global development competitiveness."

For Shift Up, the deal adds a Japanese development foothold led by one of the industry's most established directors, while extending the company's reach beyond Stellar Blade and its mobile-origin business. For Unbound's roughly 50 staff, it secures publishing and resourcing for an unannounced AAA console and PC title without an outside publisher deal.

The acquisition price and Unbound's current project timeline remain undisclosed. The clearest signal to watch: whether the teaser's monster imagery materializes into a full reveal under the Shift Up publishing label in the coming months.
