Screwfly Studios is a two-man developer based in Sydney and Melbourne, Australia. The studio, established in late 2011, is comprised of David Kidd and Logan Booker. Screwfly has released two titles since its founding: Zafehouse: Diaries, a post-apocalyptic zombie survival simulator told entirely via a dynamic journal, and Deadnaut, a sci-fi, squad-based RTS where players must explore derelict alien starships filled with randomly-generated crew logs and dangerous horrors.
