Synaptic Command Network As long as the Hive Tyrant from the Tyrant Node Formation has
not been removed as a casualty, then all other Synapse Creatures from this Formation that are
within its synapse range add 6" to their own synapse range.
The Swarm Unleashed As long as the Hive Tyrant from the Tyrant Node Formation has not
been removed as a casualty, you can re-roll failed results when rolling to see if a Termagant,
Hormagaunt or Gargoyle Brood from this Formation that has been completely destroyed is
replaced (see the Endless Swarm or Skyswarm special rules in Tyranid Invasion - Rising
Leviathan II).
