About the Game

A mix of roguelike shooter and survival on an unknown planet, featuring persistent progress and a cozy hub. Attempt to unravel the mysteries of what has happened by exploring stations, dungeons, canyons, swamps, and permafrost, while battling alien creatures. 

  • Adrenaline shooter. Each enemy is a mortal danger. Caution, reaction and aim are as important as a saved ammo and an extra explosion that raises the alarm in the den of creatures.

  • At night it's more dangerous. Survival with elements of horror. Stock up on oxygen, flashlight batteries and ammo in advance to have a chance of surviving another night.

  • Wide range of weapons and equipment. Pistols, assault rifles, shotguns, machine guns, grenade launchers, katanas, night vision, energy shields, sound absorption, weapon upgrades and more.

  • Combos and progression. Recipes for unique weapons. Enhancements that transform your character. Shops and secret rooms throughout the levels. Weapon upgrades in the hub.

  • Solo or co-op up to 4 players. Play shoulder to shoulder, protect your teammates' rear and share resources.

    Inspired by the best roguelikes like The Binding of Isaac and by the fast‑paced, dangerous vibe of Hotline Miami.
