Developed by Giraffe Cat and released in 2023 for PC and Nintendo Switch, The Sirena Expedition is a 2.5D horror platformer and puzzle-adventure set within an abandoned underwater facility discovered deep in the Mariana Trench. The game opens with a phone call drawing the protagonist to investigate something uncovered during a survey of the Sirena Deep, and from there players navigate the eerie, derelict structure in search of answers about who built it and what took place there. Rendered in PlayStation 1-inspired visuals, the experience leans heavily on a tense underwater atmosphere with horror elements woven throughout. Puzzle mechanics form a core part of progression alongside the platforming, and the game features fully voiced dialogue and an original soundtrack composed by beee girlll and Giraffe Cat. A primary run takes roughly an hour to complete, though hidden content exists for players who explore more thoroughly.
Explore a mysterious, abandoned underwater facility at the bottom of the Mariana trench. Who built it? What was it used for? Perhaps you will find answers, or perhaps the answers will find you.
