Summary of Progress: Developer Log from V19.5

All newsPlayers around this dateRead on Steam

We are excited to share the latest updates for Eternity's Echo: Patient Zero. Here are the significant technical improvements and innovations in version 19.5:

Techblade Energy Level Display


We have made an improvement to display the energy level of our Techblade on the watch on our left wrist. Now, as the energy level fills up, three boxes on the edge of the watch fill in, allowing players to easily track their energy levels. This new feature serves as a visual feedback mechanism that enables players to better plan their combat strategies.

Motel Level Progress


We have made significant progress in the Motel level. By enhancing the environmental details and playability of this area, we aim to provide a more immersive experience. The new textures, lighting effects, and interactive objects in the Motel level offer players a richer atmosphere.

Forest Level Progress


Similarly, we have made substantial advancements in the Forest level. By working on environmental details and playability, we have made this area richer and more explorable. The dynamic weather conditions, sound effects, and flora and fauna diversity in the Forest level provide players with a more realistic gaming experience.

Enemy AI Improvements


Improvements have been made to the animations of enemy AI. We have undertaken detailed work to make the movements of AI more fluid and realistic. By updating the movement algorithms of enemy characters, we have ensured they exhibit smarter and more unpredictable behaviors.

Additionally, special work has been done on enemy AI breaking through locked doors. This allows enemies to overcome obstacles in front of players, offering a more dynamic and challenging experience. This new feature adds a game mechanic that requires players to be on alert at all times, increasing the game's tension.

We are happy to push our game further with these updates. Thank you for your continued support and stay tuned for more updates!

Best regards,
The Demonsoft Games Team
