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 is approaching PC release!

Hello fellows!

We’re working hard to finish porting the game, the global status is quite promising! Although we didn’t manage before end of 2015 as we initially planned we hope to be able to start with Early Access phase shortly!

A big thing that slowed down our progress are the controls, the original game had controls optimized for touch devices, which isn’t good for a deskop game, so we worked on giving the character real physics behavior to make it more platform style, some tweaks are still to be done but the final effect is absolutely promising!

Another issue is the fact that we weren’t satisfied at all with the current tools and weapons, either aesthetically either with the mechanics, so we spent some time trying to figure how to improve the overall thing. We ended up with something that we’re sure you will enjoy, check this out:


Some inner details are still to be decided but we’re slowly finalising them!

In the Early Access phase you should expect a game that already has all the gameplay features available, but with some more delicate components still missing until we’re sure they work correctly. For example steam API integration or multiplayer, which will probably introduced some time after. This doesn’t mean that such features aren’t already implemented, but that we need time to make them work without problems!

More news coming soon!
