At the start of the first battle round, select one of the following Hyper-adaptations to be active for **^^Tyranids^^** units from your army until the end of the battle: **SWARMING INSTINCTS** Each time a **^^Tyranids^^** model with this Hyper-adaptation makes an attack that targets an enemy **^^Infantry^^** or **^^Swarm^^** unit, that attack has the **[SUSTAINED HITS 1]** ability. **HYPER-AGGRESSION** Each time a **^^Tyranids^^** model with this Hyper-adaptation makes an attack that targets an enemy **^^Monster^^** or **^^Vehicle^^** unit, that attack has the **[LETHAL HITS]** ability. **HIVE PREDATORS** Each time a **^^Tyranids^^** model with this Hyper-adaptation makes an attack that targets an enemy **^^Character^^** unit, if a Critical Hit is scored, that attack has the **[PRECISION]** ability.
This ability always takes the form **[SUSTAINED HITS X]**. Each time an attack made with a **[SUSTAINED HITS]** weapon results in a **critical hit**, that attack results in a number of additional hits on the target as denoted by **X**. ***Example: An attack made with a **[SUSTAINED HITS 2]** weapon results in a **critical hit**. That attack therefore hits the target three times (once from the **critical hit**, and twice more from the **[SUSTAINED HITS 2]** ability).
Each time an attack made with a **[LETHAL HITS]** weapon results in a **critical hit**, you can choose for that attack to automatically wound the target. ***Designer’s Note:** Choosing to automatically wound the target means that no **wound roll** is made for that attack. You may decide against this, as it means that attack cannot result in a **critical wound** and so cannot trigger other abilities such as [DEVASTATING WOUNDS].*
While resolving attacks made with one or more **[PRECISION]** weapons, at the start of the Allocation Order step (05.03), if the target unit contains one or more **CHARACTER** models **visible** to one or more of the attacking models, the active player can select one allocation group that contains one of those **visible CHARACTER** models. If they do, until those attacks are resolved, or until that **CHARACTER** group is **destroyed** (whichever happens first), that **CHARACTER** group is the current allocation group.
