After watching the credits for Pragmata, you might feel a bit lost or emotionally drained. The good news is, your adventure on the moon doesn’t have to end there. An Unknown Signal awaits, offering new challenges for you to face.
Here, you’re free to take on a series of fresh challenges and earn worthwhile rewards. It even provides a little extra ending scene if you complete everything.
How to Unlock Unknown Signal
Unlocking the Unknown Signal is easy — just finish the game. Instead of restarting from a previous save, select Unknown Signal from the main menu using your completed game save. This keeps all your progress just before the final battle.
Once you restart in the Shelter again, a new area appears on the Tram network called the Hidden Chamber. Here, you’ll find ten different challenges, each requiring a unique way to unlock. Completing all of them will reward you with various perks.
How to Unlock and Beat Every Unknown Signal Challenge
The challenge pods in the Hidden Chamber resemble the Training Pods from the Shelter. They share similar environments and can be restarted easily. However, unlike Training Pods, these challenges have no time limits or failure conditions—just a straightforward victory.
Each challenge is unlocked in a different way and contains hidden rewards. Here’s a look at all of them:
