Phalanx Sensor

In brief: “Phalanx Sensor” — a building of the “Special” category in Xterium, available from the start of the game, maximum level — 30.

(data current as of 2026-05-22, game version 2.12.7)

The phalanx is based on high-resolution sensors analyzing the spectrum of light, the composition of gases and emissions from remote worlds, followed by the transfer of information for processing in a supercomputer. By the difference in the variation of the gas composition and radiation, the presence and composition of the fleets in the zone of action of this phalanx are calculated. To prevent overheating during the scanning of the phalanx, a certain amount of deuterium is used.

Planet Anomalies 1

Planet features chosen and researched in the Planetarium (for dark matter or antimatter). Give a permanent percentage bonus to a specific effect for as long as the colony exists.

If something is missing — where to look

Contextual alternatives for specific problems. Each block is a separate problem and the buildings that solve it.

If the search radius is insufficient

Also: Upgrading the Sensor Module itself increases its range. Espionage research also affects both the range and the quality of intelligence.

What to build next

Development chain — what is worth building in parallel with or after this building.

Moon base — Required — the sensor module is built only on the Moon
