You can buy this DLC once Hush Hush is released later in 2021. It depends on how you purchase it! There are two ways. If you purchase a DLC or the Panda Pass through Steam, all you need to do is scroll down in your Steam Library until you see DLC on the right.
Click on 'Manage DLC', then check the appropriate box to enable your new content. If you purchase a DLC or Panda Pass from our website via Humble Bundle, then a code will be emailed to you. You can enter this code in-game by clicking on the 'More' tab followed by the 'Enter Coupon' button. Type or copy/paste your code in the blank field and click 'OK'. If, for some reason, you didn't receive the email, lost your code, or the code says 'Already Claimed', you may need to access your code through the Humble Bundle website instead. Log in or create an account with Humble Bundle using the SAME email you purchased your DLC or Panda Pass with, then retrieve your code from the Account Purchases screen. In your game of Crush Crush you can enter this code on the “More” tab, by clicking on “Enter Coupon”. Type or copy/paste your code in the blank field and click “OK”.
