– In-Game Description, XCOM: Enemy Unknown
A Flush shot receives a +30 Aim bonus but only inflicts 50% damage. Similar to the Suppression ability, it does not impose a turn cooldown with use but instead expends a greater-than-normal amount of ammunition – specifically triple that of a standard attack. Note that the shot does not have to hit in order to force the target to move; even a missed shot will flush the target out. If the unit was on Overwatch before being targeted, it'll be cancelled.
The new location selected by the target unit will be random, and is generally not dependent on the direction of the attack. The target may move out of cover into an open space, into better cover than they had before or even end up retreating outside of your squad's visibility area altogether.
Conversely, some enemies may sometimes not reliably be forced to move at all (though they will still take the attack damage if it connects), which seems especially applicable to flying units such as Floaters. It is currently unknown whether this is by design or is an implementation bug.
If the enemy does move, it will trigger as per normal movement rules any applicable reaction shots from soldiers on Overwatch (including via Squadsight), soldiers who are currently suppressing the target, or even Close Combat Specialists who are in range.
As there's an attached ammo cost, this ability requires the use of a primary weapon; it does not work with pistols.
Flush is also a good ability to finish off low-health enemies with, thanks to the increased accuracy. This is especially useful in a game with "Damage Roulette" enabled.
- On rare occasions the flushed target may teleport through one or more walls into a completely different area.
