Sentinel is an ability of the Support Class in XCOM: Enemy Unknown.

Allows two reaction shots during Overwatch, instead of only one.

– In-Game Description, XCOM: Enemy Unknown


  • Using the Sentinel ability is the only way for a Support to fire twice in a single turn.
  • Both reactive shots can occur in quick succession, and in many cases both shots may be fired at the same enemy, provided it is still in motion and wasn't killed by the first shot. This is usually the case, as each square traveled by an enemy during its move will serve as a separate instance of attracting Overwatch.
  • Boosting a Support's Aim stat with a S.C.O.P.E., Gene Mods and/or Medals can allow the soldier to maximize this ability's utility.
