As the lands swarm and writhe, and the skies are clouded with winged monstrosities, other foes advance unseen below. Mawlocs, Raveners and Trygons burst from the ground to emerge in the midst of clustered defenders, scything apart and devouring screaming victims before they can raise their weapons in defence, sowing crippling fear and confusion through those that witness the unexpected violence. DETACHMENT RULE SURPRISE ASSAULT Burrowing Tyranid bioforms burst from the ground in all their horror. Each time a Tyranids model from your army makes an attack, re-roll a Hit roll of 1. Each time a Burrower unit from your army is set up on the battlefield from Reserves, place a circular 40mm Tunnel Marker anywhere on the battlefield within 1" of that unit and more than 3"horizontally away from all enemy units. In the Reinforcements step of your Movement phase, when you set up a unit on the battlefield from Reserves, you can set that unit up wholly within 9" of one of your Tunnel Markers and more than 6"horizontally away from any enemy units. If an enemy model (excluding Aircraft) ends any kind of move within 3" of one of your Tunnel Markers, that Tunnel Marker is removed from the battlefield. KEYWORDS Mawloc and Trygon units from your army have the Burrower keyword. In the Muster Armies step, you can select up to 2 Trygon models from your army. The selected units gain the Character keyword. Designer’s Note: This means that the selected models can be given Enhancements and one of them can be selected as your Warlord. ENHANCEMENTS SYNAPTIC STRATEGY Possessing an exceptionally acute connection to the hive mind, this creature benefits from a constant influx of sensory data, enabling it to traverse the battlefield and emerge at the place and time of maximum impact. Tyranids model only. Once per battle, you can target the bearer’s unit with the Rapid Ingress stratagem for 0CP, and can do so even if you have already targeted a different unit with that Stratagem this phase. TREMOR SENSES From its concealed position beneath the battlefield, this bioform picks up on subtle traces of movement from the enemy force, impelling its fellow organisms to reposition themselves in preparation for a coordinated assault. Tyranids model only. After both players have deployed
