add a sonar pulse to improve environmental visibility

Sorry in advance if this has already been suggested. If that’s the case, feel free to delete this post to avoid unnecessary duplicates.

I would like to suggest adding a sonar pulse module for the Tadpole that briefly highlights the surrounding environment when exploring dark or hard-to-see areas.

The module would be installed as an upgrade on the Tadpole and could not be used while swimming.

The goal would not be to replace the need to navigate and explore without a map. The pulse could simply highlight nearby terrain, openings, caves and other important environmental features for a few seconds, making it easier to understand the surrounding geometry.

There is a difference between creating a dark and atmospheric environment and making it difficult to see what is actually around you. In some areas, it can be hard to tell whether there is a passage or an interesting area behind a rock formation, which can make exploration feel frustrating rather than rewarding.

The sonar pulse could consume some of the Tadpole’s battery, making it a useful but costly tool that cannot simply be spammed.

This would preserve the atmosphere and the importance of navigating without a map, while giving players a way to briefly make sense of their surroundings when visibility becomes a real problem.
