About this game

In an age of faster-than-light travel and advanced cyber-robotics, brave explorers known as Cosmobreeders travel to forgotten worlds and study alien creatures.
Play as a lone Cosmobreeder shot down over Planet Tutone, a world fallen to ruin and haunted by ancient betrayal. Your comrades have been captured, your equipment stolen. Armed with only your wits, traverse ancient service tunnels, eerie alien forests, and deep volcanic caverns. Reclaim your gear, uncover alien artifacts, and awaken mysterious ESPer abilities to survive the planet’s numerous dangers.
Navigate hundreds of intricate rooms, in which fragile walls hide secrets and hidden paths reward the curious. Battle dozens of unique foes and conquer epic bosses, each victory granting new abilities and allowing you to delve deeper into Tutone.
You might be on a solo mission, but you’ll never be lonely! Every rescued Cosmobreeder has a story to tell, and your support team is just a radio call away. Call up Mauser, Tomcat, or Bossu for guidance, banter, and intel on every enemy or item you discover! Meet shopkeepers and other denizens of Tutone, barter for info or equipment.

Unravel the story through dozens of hand-crafted pixel art cutscenes. Will you uncover the planet’s mysteries, or fall in battle and be captured like your comrades?
