Editing Codex - Tyranids: /tg/ edition (section)

===Instinctive Behaviour===
Individual Tyranid creatures function as tendrils of the gestalt Hive Mind; however, outside of its influence they revert to highly evolved animal instincts befitting apex predators. At the beginning of the Tyranid turn, roll a Leadership test for each unengaged Tyranid unit outside of Synapse range; each will act as normal if they pass. If not, they assume natural survival or attack patterns based on their rules matching the descriptors below:

*'''Lurk:'''
**The brood immediately seeks the nearest cover, be it ruins, buildings, or other terrain. It may shoot only if it has reached said cover; otherwise, it must continue to the nearest cover by using a Run move. It may not charge in the Assault phase. The unit gains the Stealth special rule.
**'''Synaptic Bonus - Sensory Synchronization:''' The unit gains the Stealth special rule.

*'''Hunt:'''
**The brood must shoot at the nearest enemy unit to which they have line of sight and may not charge in the Assault phase. The unit gains the Preferred Enemy special rule.
**'''Synaptic Bonus - Collective Guidance:''' The unit gains +1 BS.

*'''Feed:'''
**The unit may not Run or Shoot, but must charge the nearest viable enemy unit in the Assault phase. It also gains the Rage special rule.
**'''Synaptic Bonus - Neurokinetic Acceleration:''' The unit gains +1 A.
