What the developers have to say:

Why Early Access?

“Signal Decay is still in rapid development. The core game mechanics have been established through hundreds of playtests, along with considerable contents. Early Access will provide us with insights on further tweaking the game system, designing smooth tutorials for everyone, and creating intriguing contents. We also hope to build a community early for Signal Decay through EA.”

Approximately how long will this game be in Early Access?

“Signal Decay will be in Early Access for 8 months, give or take a few months.”

How is the full version planned to differ from the Early Access version?

“The full version will add more story experience, with a full tutorial, more diverse weapons and gadgets to pick from, more enemies and level mechanisms, and a better overall experience.”

What is the current state of the Early Access version?

“The Early Access version has local multiplayer mode, online mode and single-player mode. The stealth system, relationships between different equipment and enemies, tech trees and the dynamic world system have been iterated for years, which provides a solid and unique experience.”

Will the game be priced differently during and after Early Access?

“Yes. Since the Early Access version has less content than the full version, the full version will have a higher price.”

How are you planning on involving the Community in your development process?

“The feedback from the community is crucial to the success of Signal Decay. We will be taking in their feedback regularly and will be posting updates at an appropriate time interval through our newsletter, social media and other channels.”
