What the Dev said about their game.
This terrifying first-person horror experience immerses the player into a world of isolation, fear, paranoia and claustrophobia as you make your way through the Oberon Cave. Throughout the game, you will experience atmospheric environments, disturbing audio and horrifying visuals.
In a remote cave deep in the wilderness a team of amateur spelunkers set out to explore its mysterious depths. It's not long until their excitement turns into terror as they delve deeper into the darkness, they soon stumble upon a terrifying discovery.
Equipped with a trusty headtorch, you must explore the regions of the cave in search of your brother and his friends. Cassiculus features no combat. This experience focuses primarily on atmosphere and dread. There are multiple cutscenes to encounter, items to discover and other secrets along the way.
You can play the game for free on Steam.
