Action Rules
A normal turn will have the unit doing Move + Fire (or other Action). The soldier's class and abilities also determine the options available for each Actions. The following rules are a brief summary of how Actions work:
- A unit may perform 1 or 2 Actions each turn.
- Some actions (firing Sniper Rifle or Rocket Launcher) may only be performed as the 1st Action in a turn.
- A unit's turn automatically ends after the unit:
- Performs any other action other than Move on its 1st Action.
- Performs a 2nd Action after moving as the 1st Action.
- The following Abilities change the above rules:
- Bullet Swarm - Heavy can Fire + Fire/Move/Surpress/Overwatch.
- Double Tap - Sniper can can Fire + Fire.
- Run & Gun - Assault can Dash + Fire but not Dash + Equipment.
- Snap Shot - Sniper can Move and Fire with a Sniper Rifle.
Tactics
- Overwatch: Overwatch only allows a shot against the first unit spotted. For example, if you put a soldier on overwatch and they fire at the first enemy to move, any subsequent enemies moving through that soldier's line-of-sight will not be fired upon. The same applies to aliens overwatching against you.
