What's all this about?

SpaceChem is an addicting, design based puzzle game by Zachtronics Industries that has challenged, frustrated, and elated thousands of gamers. Now, Zachtronics needs your help to fund production of the limited physical edition of SpaceChem.

Each limited edition copy of SpaceChem includes:

  • The 63 Corvi DLC (previously available only on Steam and GOG) 
  • A printed CD key insert
  • A printed SpaceChem periodic table 
  • Endless hours of chemical engineering fun!

Our Goal

We have set a goal of $600 to cover production costs. It is likely that this limited edition will only be available through this Kickstarter campaign.
