Suspends Play – A card which specifically says it “suspends play” may be played at any time during the play phase (even during your opponent’s turn) and may interrupt and temporarily suspend any action. Using a special download icon also suspends play.

After the card play or special download has resolved, the suspended action resumes.

See downloading – special download, actions – interrupting

If no action is in progress, an action that may suspend play (such as using a special download icon) does not suspend anything.

You may not suspend play during the seed phases.
