XEU Heavy Suppression

Suppression is an ability of the Heavy Class, Thin Men, Heavy Floaters, and Mutons in XCOM: Enemy Unknown. S.H.I.V.s of all types also gain this ability once S.H.I.V. Suppression is researched. The Support Class can be trained to use a functionally identical ability, Rifle Suppression.

Can fire a special shot that grants reaction fire at a single target. The target also suffers a -30 Aim penalty.
– In-Game Description, XCOM: Enemy Unknown


Suppression can be useful for pinning down a big target, especially if your soldiers are otherwise unlikely to hit or kill it. This can buy you time to get soldiers to cover or into position to flank the alien. Suppressive fire also sometimes destroys the enemy's cover, leaving the enemy exposed to fire (and increased critical hit chances) from the rest of your team.

The ammo consumption for using Suppression is twice that of standard Fire. Also, in most cases, the AI is smart enough not to move while suppressed (avoiding triggering the reaction shot); this is especially true on the higher difficulties, where aliens will frequently land shots despite their Aim penalty or will use an alternative to shooting (such as a grenade, Overwatch, or psionics) to get around the Aim penalty.

Where Suppression shines is how well it synergizes with Heavy Class abilities from the right side of the promotion tree. Holo-Targeting + Suppression reduces the alien's Aim while simultaneously increasing your soldiers'. Danger Zone + Suppression increases the Suppression effect from a single target to a small area, which can result in you Suppressing multiple targets at once and (potentially) granting you reactive fire on any one of the targets. Mayhem + Suppression offers minor, reliable AoE damage with Suppression; this is especially useful for mopping up multiple weakened aliens or getting a small amount of guaranteed damage when a regular shot is unlikely to hit. Combining these abilities with the use of Suppression makes Suppression a very flexible and worthwhile ability.


Some aliens that cannot use Suppression in single player mode, such as Sectoids and Sectoid Commanders, can use it in multiplayer.

Xcom - Suppression not usable (bug?)


Sometimes it's not possible to use Suppression even though a normal shot is available. Even with a target visible and the Fire option available, clicking on Suppression shows the message "No targets within range." The same has been observed with the Support class Rifle Suppression skill. See video for demonstration.
