Mutable Carnifex

At the start of the Tyranid turn any broods outside Synapse countrol range must take a Morale check for being All On Your Own. If failed consult the Tyranid Instinctive Behavior table. Additionally, roll on this table if a Tyranid creature fails a normal Morale or Pinning test while outside the Synapse control range.

The opposing player's line of fire is only blocked by terrain, vehicles and models in close combat while shooting at Tyranid models.

-Automatically passes any Morale checks and cannot be pinned


-Can allocate close combat attacks to a specific enemy in base-to-base contact and shoot at enemies not targeted by it's joined unit


-May re-roll Difficult Terrain unless joined to a unit


-Ignores enemy Armor Saves in close combat and roll S+2D6 for vehicle armor penetration


-Counts as a unit of troops for victory conditions

If the Tyranid player gets to choose the scenario then the Tyranids will automatically be the attackers and must choose a scenario from the category of Battle.
All three missions under Battle use the Deep Strike rule, and all models in the Tyranid Seeding Swarm must arrive on the table by this method. The exception are Tyranid broods with the infiltrate rule and Lictors.
For all other scenarios, if the Deep Strike option exists it can only be used by Tyranid units with the Deep Strike rule.
