Twilight Imperium: Cuarta Edición

Fighters do not count toward your fleet pool limit; they instead count against a system’s capacity (page 20).

You can score objectives during the action phase at any time and during the status phase in the Score Objectives step; you can score a maximum of one public and one secret objective each status phase, you may score any number of objectives during a turn of the action phase but only one objective during each combat (page 17).

After the active player resolves a strategic action, each other player may resolve that card’s secondary ability by spending a command token from his strategy pool, except the Leadership card’s secondary (Leadership does not require spending a command token) (pages 9, 15).

If a combat results in all units of both players being destroyed on a planet, the defender retains control of the planet and places one of his control markers there (page 15).

Space Cannon can be used after the Move Ships step (Space Cannon Offense) and during the Invasion step (Space Cannon Defense); space cannon rolls are not affected by rerolls, combat modifiers, or other combat roll effects (pages 20–21).

Anti‑Fighter Barrage is resolved simultaneously by players at the start of the first round of a space combat (immediately before retreats) and cannot be used in subsequent rounds (page 22).
