The Croatian team Summer Eternal, consisting of former ZA/UM members Argo Tuulik and Dora Klindžić along with local developer Aleksandar Gavrilović, is working on an RPG currently titled Red Rooster.
Instead of a traditional announcement, the game will be presented through the book Summer Eternal Anthology Volume One, available for order at a price of €69. The book will feature concept art, essays, and interviews, and alongside the standard edition, there will be a deluxe package with a vinyl record and collectible content. The game announcement is planned for summer 2026.
