Announcement of Joint Game Development Agreement

NGJ Corporation (“NGJ”) is pleased to announce that it has entered into an agreement with iDiOSLAB for the joint development and worldwide release of the game title Delve Survivors: A Dungeon Roguelike.

Delve Survivors: A Dungeon Roguelike is a turn-based roguelike developed by iDiOSLAB, a team of developers based in Japan and the United States.

The game is currently in development as a unique fusion of the strategic depth of traditional roguelikes and the build-crafting mechanics and large-scale enemy encounters that have made survivor-style games increasingly popular in recent years.

The title is currently being developed for Steam, with future releases planned for Nintendo Switch, Nintendo Switch 2, PlayStation 5, and other platforms.

The game has also been selected for the official Steam event “Steam Bullet Fest 2026.” English and Japanese demo versions are scheduled to be available during the event, which will run from June 8 to June 15, 2026 (Pacific Time).

Through promotional activities and participation in major gaming events in Japan and overseas, including Gamescom in Cologne, Germany, Tokyo Game Show (TGS), and Steam Next Fest, NGJ will continue working to expand awareness of the title.

NGJ operates an aggregation business focused on discovering, supporting, and bringing Japanese indie games to global markets.

Delve Survivors: A Dungeon Roguelike is positioned as the first project under this initiative.

The game is planned to support 11 languages. DICO Co., Ltd. will be responsible for localization, LQA, and porting for Nintendo Switch, Nintendo Switch 2, and PlayStation 5.

NGJ is also working with multiple overseas publishers and distribution partners to develop sales opportunities, particularly across Asian markets.

NGJ will continue contributing to the international competitiveness of the Japanese game industry and the creation of new intellectual properties by bringing outstanding Japanese indie games to audiences worldwide.
