Abdication is a puzzle game for PC released in April 2023. However, recent coverage indicates confusion around the title: Jeff VanderMeer, creator of the Southern Reach sci-fi series, has announced Abdication as the fifth and final novel in that book franchise, which began with Annihilation in 2014. It's unclear whether the game shares thematic or narrative elements with the literary project, or if the naming overlap is coincidental. Coverage of the game itself remains limited at this time.
