What new Tyranid adaptations are being discussed?
Short answerAdaptations against daemons and other warp-related entities are described, making a simple Chaos-versus-Tyranids solution less convincing within the scenario.
NotesThe Tyranids are credited with adaptations against daemons and other incorporeal, warp-related entities. This complicates the earlier suggestion that conflict with Chaos would reliably weaken their forces. A further proposal to move the hive fleets into the warp is treated sceptically and turns into joking speculation. The exchange concerns the fictional setting, and its hive-fleet identification is not independently established.
