Life and Tech Signatures

NOTICE: This page is a Work in Progress as much of the lore/Development for the game is yet to be established.

Life Signatures and Tech Signatures are key indicators detected by a starship's Sensors in Starship Simulator. They signify the potential presence of biological life or technological activity, respectively, on planets or other celestial bodies within a star system. These signatures are crucial outputs of the Galaxy Generation system and play a vital role in guiding exploration and discovery. Understanding how to effectively operate the Sensors Station is fundamental to finding and interpreting these signatures; see the Tutorial:Sensors page for guidance on sensor operation.

Tech Signatures

Definition: A Tech Signature indicates the strong possibility of technological civilization. This could be based on detecting artificial energy emissions, structured radio signals, large-scale non-natural constructions, atmospheric pollutants inconsistent with natural processes, or other phenomena that suggest intelligent, tool-using life.
Detection: Tech Signatures are relatively easier to detect over interstellar distances. They typically require only Level 1 Knowledge of a celestial body, achievable via a standard Long Range Survey using the Sensors suite (as implemented in Build 0.225.0.63 and refined in Build 0.225.0.69).
Indication: While not definitive proof of a specific civilization's nature or level, a Tech Signature flags a world or system as highly likely to host or have hosted technological life, warranting further investigation.
In-Game Display: Represented by a "Tech Sig" indicator on the Sensors UI. The ability to toggle the display of tech signatures on the Short Range planet map view was also added (Build 0.225.0.52).

Life Signatures

Definition: A Life Signature indicates the confirmed presence of biological life. This is likely based on detecting complex organic molecules, specific atmospheric compositions considered biosignatures (e.g., high levels of free oxygen alongside methane, suggesting biological regulation), or other complex patterns inconsistent with purely geological or chemical processes.
Detection: Confirming a Life Signature requires much more detailed, closer examination. It typically requires Level 3 Knowledge of a celestial body, achievable only via a dedicated Short Range Scan using the Sensors suite (as implemented in Build 0.225.0.69). The underlying "Has Life?" flag for planets was added earlier (Build 0.225.0.30).
Indication: Confirms biological processes are active. This could range from microbial ecosystems to complex flora and fauna. It does not automatically imply sentient or intelligent life, nor does it necessarily correlate with a Tech Signature (a world could have life but no technology, or technology but no easily detectable biological life signs).
In-Game Display: Represented by a "Life Sig" indicator on the Sensors UI (Build 0.225.0.69).

Gameplay Significance

Guiding Exploration: Tech Signatures, being detectable at long range, serve as primary signposts directing players towards potentially inhabited systems or worlds with remnants of past civilizations.
Prioritizing Scans: The differing knowledge level requirements encourage a tiered scanning approach: Long Range sweeps for Tech Sigs, followed by Medium and detailed Short Range scans of promising targets to confirm details and search for definitive Life Sigs.
Mission & Narrative Context: Discovering these signatures can trigger specific mission objectives (e.g., "Investigate Tech Signature," "Analyze Biosphere"), form the basis for First Contact scenarios with alien civilizations, or provide valuable scientific data.

Development Notes

The systems for generating and detecting Life and Tech Signatures were implemented and refined over several Dev Builds, particularly around the overhaul of the Sensors system and Galaxy Generation enhancements detailed in builds like 0.225.0.30, 0.225.0.63, and 0.225.0.69. The exact parameters triggering these signatures and their full range of gameplay consequences are part of the ongoing development.
