Junk Jack

Junk Jack is a sandbox game about building and improving a home, exploring procedurally generated planets, crafting items and collecting creatures and treasures. You can play online with friends or use Creative mode to build freely.

Explore the planets

Portals take you to 12 planets, each with a unique hand-crafted environment. Worlds are procedurally generated and differ each time you create a new one. Explore to find monsters to fight, crafts to learn and loot to equip or display at home. A dynamic day-night cycle and weather effects shape each world, alongside a coloured lighting system.

Build and craft

You can place hundreds of objects, blocks and decorations, and use more than one thousand different crafts. Crafting uses either a crafting grid or a simple mode that makes items with a single click. The electronics system lets you build intricate contraptions, including complete CPUs. You can also craft hundreds of potions at the chemistry bench, make furniture sets and use explosives, signs and paintable objects.

Collect and care for creatures

Tameable pets follow you around, while cows, sheep, pigs and other animals can be captured and bred. You can farm exotic plants, use them in recipes, and mix flower seeds to grow thousands of flower combinations. Catch fish and display them, along with other captured animals, in fish tanks.

Customize your home

The equip system includes hundreds of wearable items with unique stats. You can collect loot and rare treasures, display equipment on mannequins and place treasures on shelves. Customizable furniture sets, paintable objects and other decorations let you personalize your home.

Combat and guidance

Fight hordes of monsters using different weapon types. An in-game tutorial covers the basics, and the game also includes retro-style pixel art and music by Bright Primate.
