  • An Alliance must be played by the receiving player as soon as it is received. It cannot be kept secret.
    • If the active player receives an Alliance, they cannot then attempt to trade it with another player. It must be played immediately.
  • Alliance is returned when the system is activated, even if the active player will perform no hostile acts towards the other player this turn.
  • If an effect other than activating a system during a tactical action places a command counter in a system with the other player’s units, this will not cause Alliance to be returned.
  • Activating a system containing only a player’s structures will still cause their Alliance to be returned.
