Bioships Adaptations

• Battle Field Gothic [Core Rulebook]:

"We fought them the first day, and our guns tore through them with ease. We fought them the second day and saw our missiles bounce off a thickened skin they seemed now to bear, so we turned out lances on 'em. We fought them the third day, and no cursed thing worked!

...

As the hive fleet sails relentlessly on through space, it is continually evolving to meet the enemies that it faces. Individual organisms adapt and refine themselves with each new encounter, while the hive ships perpetually alter the morphology of the new organisms birthed by the fleet. As such, the hive fleet is a continually changing mass, both individually and collectively.

• 5th Ed Codex [Tyranids]:

"The Battle of the Sol'ai Rift. Kor'O'Vanan's fleet engages Hive Fleet Gorgon as it leaves the Ka'mais system. The battle initially goes well for the Tau, but they are forced to withdraw after encountering a cluster of Ramsmiter and Razorfiend bio-ships with nigh-immunity to the Tau's ion weaponry. Before the Tau fleet withdraws, they succeed in killing many of Gorgon's Narvhals, hoping to buy additional time for Kel'shan to fortify against the Tyranids."
