Ultros is a sci-fi Metroidvania set on a trippy, psychedelic Uterus floating in space called The Sarcophagus. After mysteriously waking up from a crash landing, players must navigate The Sarcophagus' eternal black hole loops and strange, alien ecosystems. Some players may also recognize the neon, eccentric art style of visionary artist and musician Niklas Åkerblad, a.k.a. El Heurvo, from the influential success story Hotline Miami. Understanding the reasons behind Ultros' looping world is another part of its unfolding mystery, as players gradually learn more about the nature of its inhabitants and beyond.
