The Ichnaea is a specialized utility structure designed to detect cloaked or stealthy ground units within a large radius. Its passive seismic sensing makes it invaluable for early warning and counter-stealth strategies.
This building has no offensive capabilities but plays a critical role in securing your territory from infiltration or ambushes.
Best used for: Revealing cloaked units, securing base perimeter
Avoid: Front-line use without support, since it cannot defend itself
