Junk Jack

Junk Jack 3.0 Update is out!



Hello! Today we're releasing a big content patch which adds more than 250 treasures to be discovered, we call it the treasure hunt season! We also added a new end game planet named Tor which can be reached from Mykon, with lots of new monsters, equip pieces, treasures and blocks.

Planets have been tweaked and should be more varied and fun to explore, we redrawn a lot of mobs and made many balance tweaks and bug fixes.

We're quite satisfied with the progress made to the game and we think the game is mature enough to be released in full form on Steam, so please let us know what you think of this patch!
After the release we'll continue with the updates, to improve Junk Jack even more.

Happy treasure hunting!

Junk Jack 2.9.1.5 is out!

Hello miners, it's patch day!

This version adds new procedural mobs, a scalable viewport option, new potions, new spear and bow mechanics, treasures drop rate tweaks and many more features and fixes.

The new spear weapons mechanic is experimental and the whole spear graphical approach will be tweaked in the future, we're thinking about increasing their length to make them able to reach more distant positions while making them less effective for short range combat.

The new procedural mob generation is experimental too, we tested it with slimes to understand the potentiality of generating different flavour of mobs by composing parts, we'll extend this feature whenever possible to other creatures if it satisfies us and especially you!

The Linux version is under heavy development and we're in a good state so hopefully we'll soon release it!

Have fun playing!
