Biotide

The following units do not split into separate units in the Form Boarding Squads step:
- ^^**Hormagaunts**^^
- ^^**Neurogaunts**^^
- ^^**Termagants**^^

You can include up to two of the following unit:
- **^^Winged Tyranid Prime^^**

You can include up to three of each of the following units:
- **^^Hormagaunts^^** (10 models)
- **^^Neurogaunts^^** (10 models)
- **^^Ripper Swarms^^** (3 models)
- **^^Termagants^^** (10 models)

- The **^^Ripper Swarms^^** unit loses the Deep Strike ability.
- The **^^Termagants^^** unit loses the Skulking Horrors ability.
- The **^^Winged Tyranid Prime^^** model loses the Deep Strike ability.

Each time a **^^Tyranids^^** unit from your army moves, models in that unit can move through friendly **^^Tyranids^^** models as if they were not there. In addition, each time a **^^Tyranids^^** unit from your army attempts to operate a closed Hatchway, if your opponent tries to prevent it, add 1 to your result of the roll-off.

Units from your army with the Shadow in the Warp ability retain that ability.

Units from your army with the Synapse ability retain that ability and gain this one.

When measuring whether a unit from your army is within Synapse Range of a friendly **^^Synapse^^** model, Walls and closed Hatchways are ignored.
