Infinitesimals Sci Fi Game Features Tiny Heroes in Giant Worlds

Cubit Studios is developing Infinitesimals, a third-person sci-fi action-adventure game set to launch in 2026. Published by Epic Games Publishing, the game places players in the role of Captain Awkney Relinrake, a tiny alien squad leader stranded on a mysterious planet after a catastrophic crash. The player character is only about eight millimeters tall, navigating a vast world filled with towering terrain, giant wildlife, and deadly mechanical sentinels known as Hunter Gatherers.

The game leverages Unreal Engine 5 to deliver stunning visuals that bring the lush, oversized environments to life. Players explore dense forests, subterranean ruins, and expansive landscapes while facing threats from hostile fauna and robotic enemies. Combat is dynamic and cinematic, with options to engage directly or use stealth and evasion tactics. Players can upgrade weapons and armor, customize gear with attachments like suppressors and optics, and utilize vehicles such as jetpacks and the POD combat vehicle to traverse the world quickly.

The narrative centers on uncovering the fate of the player’s missing squad and the vanished colony they were meant to join. The story explores themes of loss, hope, and survival in a richly developed sci-fi universe. Players must locate and rescue their scattered crew to rebuild strength and confront the mechanical threats dominating the planet. The protagonist’s British-accented voice adds humor and personality to the emotional journey.

Development and Inspiration

Cubit Studios began conceptual work on Infinitesimals in 2013, focusing on animations, videos, and music. Full-time development started in 2019, supported by UK government funding and Epic Games’ full game funding from 2020 onward. The game’s concept draws inspiration from the beauty of nature at macro and micro scales, combined with sci-fi elements and insect-level character design.

The developers emphasize player choice, allowing combat or stealth approaches, and encourage exploration of the vast, dangerous environments. The demo experience highlighted the challenge of navigating oversized flora and fauna, using scanning tools to detect life signs, and engaging in precise combat against robotic enemies and giant bugs.

Infinitesimals promises a cinematic, character-driven story with rich world-building and dynamic gameplay mechanics. Its launch on PC, PlayStation 5, and Xbox Series X|S in 2026 positions it as a highly anticipated title for fans of sci-fi action-adventure games.
