Tactical InfoEdit

  • Thrown like a grenade
  • Emits sounds that correspond to alien tactical cues
  • Causes aliens within radius to approach the beacon for 2 turns
  • Enemies already in combat are less likely to be fooled


The Mimic Beacon is thrown like a grenade, and lures all aliens that haven't been discovered to its position. Enemies that have been engaged are less likely to fall for the lure, with the exception of melee-based enemies and Mutons; lured enemies spend both action points moving towards the beacon, even if they're right on top of it. The Beacon has two uses per mission, with Deep Pockets granting three uses.

This device can be useful to draw enemies to positions out of cover and away from civilians in Terror Site missions, especially Chryssalids. If absolutely necessary, it can temporarily distract the Chryssalids in the Site Recon Council mission and facilitate the squad's escape to the extraction zone, though if the mission is given late enough for the player to have access to Mimic Beacons, by this point the already-researched tech should make this a redundant failsafe.
