XEU Stealth Satellites project

Stealth Satellites is a Foundry project in XCOM: Enemy Unknown.

In-Game Description Edit

By studying the communication signatures of the UFO nav computers we've recovered, we could update our satellite network to mimic the alien communications. This would make the satellites much harder to detect if the aliens were to go looking for them.

  • If a UFO is detected over a country covered by an XCOM satellite, and the UFO is not shot down, it makes two passes:
    • Without the upgrade, there is no protection against the UFO detecting and destroying the satellite.
    • With the upgrade, there is only a 25% chance of the satellite being detected on the first pass, and a 50% chance of detection on the second pass. [1]
