Certain actions will trigger reaction fire from aliens; others will not, even though they may reduce your TUs. (However, if you have used up several TUs doing "safe" actions then conclude with a reaction-triggering one, an alien with sufficient TUs will make several "stored up" reaction shots against you.)

The following is a (possibly incomplete) list of which actions will and will not trigger reaction fire. Opposing units also need to be facing your unit(s) and have sufficient TUs available; see Reaction fire formula for more details.


Will trigger reaction shots from an alien facing you:

  • Firing any weapon
  • Kneeling
  • Any walking/flying movement
  • Using a lift
  • Throwing any object

Will trigger reaction shots from an alien not facing you:

  • Hitting an alien (they will spin around and return fire)

Will never trigger reaction shots:

  • Turning in place
  • Firing a weapon from beyond the alien's visual range
  • Taking any action (including firing a weapon) from a position hidden to the alien
  • Priming a grenade
  • Firing at (but missing) an alien not facing you
  • Any action on the inventory screen (moving, dropping or picking up objects; loading or unloading a weapon)
  • Using a Medi-Kit, Mind Probe or Motion Scanner
  • Using a Stun Rod (walking toward the alien is what gets you killed!)
  • Being the first unit to enter an alien's line of sight. This means you can safely walk through a door, even with no TUs left! It's your next action that will get you killed. (Subsequent units which enter the door will also get shot at -- the alien is no longer "surprised".)
