Summer Eternal is an artistic collective founded in Zagreb in 2025. It brings together video game creators who previously worked on “Disco Elysium”, alongside professionals from different areas of audio and visual production. Its members include composer Corvad, whose music appears in “The Batman”, and Betty Jiang, who created concept art for Guillermo del Toro’s “Frankenstein”. The collective also includes the band Nemeček, producer Martin Tisanić and illustrator Dominik Zdenković.

Summer Eternal operates through an experimental organisational structure combining elements of a workers’ collective, consumer association, co-operative and corporation. Its working model and manifesto have attracted the attention of international video game media, while the collective has also been featured in publications including the Financial Times and The New York Times.
Before releasing its first game developed within this new structure, titled “Red Rooster”, the collective published “Anthology Volume One”, a book and vinyl record that expand the game’s world.
The collective is led by game director Argo Tuulik, winner of a BAFTA award for video game narrative; creative director Dora Klindžić, a physicist and writer whose work has appeared in Clarkesworld and Fireside; and chief operating officer Aleksandar Gavrilović, formerly head of Gamechuck and the CGDA.
