About this game

ULTROS: DELUXE EDITION

Enhance your somatic sensory input with the Ultros: Deluxe Edition – including the Ultros Digital Artbook, showcasing the psychedelic world through never-before-seen imagery from the visionary El Huervo, and the Ultros Original Soundtrack, blending Peruvian instruments with classic orchestral themes, lovingly orchestrated by Oscar “Ratvader” Rydelius.

About the Game

You wake up stranded, after seemingly crashing your ship on The Sarcophagus — a giant, space-drifting, cosmic uterus holding an ancient demonic being known as ULTROS. Trapped in the eternal loop of a black hole, you will have to explore The Sarcophagus and meet its inhabitants to understand the part you play.

Are you the gruesome breaker of this cycle, or can you become a link from destruction to rebirth?



ULTROS is set in a multifaceted realm - a vast alien landscape teeming with life. Grounded in science fiction, ULTROS comes wrapped in an eccentric art style and a mystical soundtrack from the visionary El Huervo, renowned for his work on Hotline Miami. ULTROS explores meta-themes of mental health, life, death, and karmic cycles through deep lore and environmental storytelling.



Experience brutal, intimate, close-quarter combat with cosmic lifeforms, driven by a sense of urgency – where precision is paramount and every cut of your blade counts. Yet this intense combat is juxtaposed with cultivating the greenery and tending to plant life in The Sarcophagus, providing precious moments of contemplation and peace. In turn, this grants deeper access to obscured paths.



The rich world of ULTROS holds many secrets for those curious enough — and fearless enough — to seek them out. A unique loop-based mechanic will allow you to start over at key moments in the story, providing opportunities to unfold such secrets, unlock different areas of the world and new abilities on a branching skill tree. Experiment with and master your own specific fighting style as you explore the world of ULTROS. Each loop brings you closer to the truth...

  Overlooked Metroidvania Ultros is the anti-Silksong, which makes it the perfect follow-up to Team Cherry's epic

You could opt for a newcomer like MIO: Memories in Orbit, or established staples such as Bloodstained, Rain World, or Nine Sols. But I'm going to recommend Ultros, which handles the genre in a unique manner that took me a little while to warm to, only to grow into an experience I'll treasure for many years to come.
