In Infinity games, thanks to the Automatic Reaction Order (ARO) mechanic, players never stop making game-altering decisions. Even during their opponent's Active Turn, they can take actions as their figures and Markers react to enemies activating with Orders.

A trooper owned by the Reactive Player can declare an ARO if any of the following is true:

  • It has Line of Fire (LoF) to a trooper being activated by the Active Player.
  • An enemy trooper activates within its Zone of Control (ZC).
  • It has a Special Skill or piece of Equipment allowing reaction to enemy actions without LoF.

The Reactive Player must declare AROs for all eligible troopers immediately after the Active Player declares his Entire Order or the first Short Skill of his Order (see: Order Expenditure Sequence). Troopers that fail to do so lose their ARO against that Order. If, by declaring the second Short Skill of its Order, the active trooper gives ARO to enemy troopers that did not have ARO against the first Short Skill, then those enemy troopers can declare their AROs.

Each time the Active Player activates a trooper by spending an order, each eligible enemy gets one single ARO, regardless of the number of Skills the Active Player declares during that Order.

AROs must choose the trooper activated by the Order as their target.

Troopers cannot react to AROs, since only the Active Player's Orders give AROs and only the Reactive Player can declare AROs.

There is no limit to the number of troopers that can react to the activation of a single enemy trooper.

IMPORTANT!
Using an ARO, the Reactive Player can only declare Skills that specifically state they are usable in ARO.

ALL AT ONCE

In Infinity, Orders and AROs are simultaneous regardless of the Skills declared.

For example, if an activated trooper declares Move + BS Attack and chooses to shoot from its starting position (taking advantage of a favorable Range), and its target reacts with a BS Attack, choosing to shoot at the end of the Movement (again, for Range purposes), then both actions are still considered to be simultaneous for all game purposes.

IMPORTANT!
All AROs are also simultaneous. This means that, if a Camouflage Marker spends an Order to Move, its opponent can declare Discover with all troopers with LoF to it, but cannot declare Discover with one of the troopers and BS Attack with the rest, waiting for the Discover Roll to be successful (see: Camouflage and Hiding).
