OpenClonk 2.0 released

It’s been 9 months since the last full release. Time for another one! The most visible changes since 1.2 are:

  • The landscape is drawn in higher resolution
  • The Macosx port has an editor like the other ports
  • A new scenario Scorched Garden, and a redesigned Overcast

But there are a lot of smaller changes and improvements as well, especially for people who want to write their own game content.

You are advised to first uninstall OC 1.2 before you install OC 2.0 as the game data of it is incompatible with the previous version.

This version shall be the foundation on which finally the mines, production lines and generally the settlement is implemented. The start signal has already been lit with this forum post from Clonkonaut. If you are interested to contribute, just talk to him or reply to this forum post.

  1. Certain someone says:

    Sounds awesome, will test it later.

  2. Smartass says:

    Nice now thats a big Update, i will test it right away!!!

  3. dima says:

    Sounds happy. Unable to run binary file.

  4. Smartass says:

    The Graphics looks Nice and the Animations are smooth, but my Logitech Controller(F310) cant be calibrated(also i cant Throw), and i must make a new Player(hmm its not that big Problem, cause in the first version lvling was WAY faster(Bug?).

    Also i hope in the next version i can Calibrate my Controller!

  5. Newton says:

    dima: What operating system do you have and which file did you want to run? What error message do you get?

    Smartass: Currently it’s not possible to calibrate or change the controls. See here: – that you can’t throw at all is most probably a bug. Could you make a more detailed report in our bugtracker here: ?
    That you have to create a new player is not a bug, the file extension of the game data files has been changed since 1.2.4 because it lead to problems with earlier versions of the game (namely Clonk Rage) as it uses the same extension for its files even though the game data is completely incompatible with each other. This is why it is advised to deinstall the old OC first before installing the new one.
