About This Game

As a novice space miner, you have been assigned to work on an unexplored, distant planet. With little local fauna and a poisonous atmosphere, it shouldn't be much of a problem to expand your base and extract valuable resources. It shouldn't...

Throughout the day, discover new deposits of raw materials, mine and process them in advanced refineries. From the materials you acquire, create new tools and weapons. Repair damage and expand your base with additional modules - these are all keys to success.


At night, you must defend your base from attacks by monsters that want to destroy everything you've built. Shoot and use a variety of weapons including a variety of turrets with deadly weaponry. Do your best to fend off the advancing waves of terrifying beasts and defend your outpost.


Develop your character by acquiring new skills and equipment needed to expand and defend your base. Explore the environment and the procedurally generated underground. Gather skills, experience and technologies that will help you reach deeper and deeper with each new game and discover more mysterious artifacts. With them, new opportunities, challenges and tactics will open up for you in the next game. The variety of options will make you want to fulfill your mining contract more than once.

Your goal is to gain wealth, replenish your supplies and escape from this dangerous planet or build a fortress to resist all enemy attacks. You must take care of your well-being, adequate water, oxygen and food. Decide whether you want to take care of the environment of this alien planet or set your sights on making the most profit. Will you be able to survive this cosmic challenge in this dangerous and mysterious world?

  • Survive: take care of your health, food, water and oxygen.
  • Dig deep: obtain raw materials, explore more and more procedurally generated decks
  • Make progress: discover hidden artifacts and technologies to access new abilities in subsequent games
  • Take care of your outpost: build, upgrade and repair your base. Craft useful items.
  • Eliminate aliens: either on your own or with a series of automatic defense turrets
  • Players: play alone or cooperate in a team of up to 4 friends

  • Want to do everything yourself? OK - progress will be slower, but greater satisfaction.
  • Want to automate all processes as much as possible? OK - create mining robots, transport robots or a chain of defense turrets.

  • Want to play alone? OK - do everything at your own pace, with the ability to save the game and continue it.
  • Want to play with a bunch of friends? OK - form a close-knit team together to meet the demands.

  • Want to have a nice time? OK - turn off your opponents, reduce negative interaction and enjoy a relaxing game.
  • Want a challenge? OK - accept the toughest mining contracts and face adversity.

  • Want perfection? OK - Refine your tactics and every element of your base in a repeatable environment to achieve the highest possible score
  • Want variety? OK - enable random generators to make each game a new surprise.

  • Do you want to kill monsters by yourself? OK - pick up a rifle and try to survive
  • Want to create the ultimate line of defensive turrets? OK - create a chain of perfectly complementary cannons so that even a space mouse won't slip through.
