Tyranids read FAQs v 1.2

I waited so long for these and I got it! Now gants deploy 6" from spore!!! Yeah, anti-blast deployment! No more punishment from blasts and flamers!!!

Once a Mycetic Spore has landed, all creatures within must immediately deploy – place the unit such that every model is wholly within 6" of the Mycetic Spore.

No more cover from Vector Strike! Tyrants say thank you to GW.

Random Allocation. Against vehicles, these hits are resolved against the target’s side armour. No cover saves are allowed against these hits.

Now only models in range can be shot down! Not great for tyranids, as our shooting is a short one.

Q: When making a Shooting attack against a unit, can Wounds from the Wound Pool be allocated to models that were not within range any of the shooting models when To Hit rolls were made (i.e. half the targeted model are in the shooting models’ range, and half are not)? (p15)

A: No.

Now we can act normally after gone to ground if we became fearless!
Put unit without synapse in cover, go to ground easily. In your turn, bring synapse to your unit and then move, shoot and assault normally!!!! Awesome!!!

Q: If a unit has the Fearless special rule applied to them while they have Gone to Ground, are the effects of Go to Ground immediately cancelled (for example, if this were to occur at the start of their turn could those units then move, shoot etc. as normal in the appropriate phases?) (p35)

A: Yes.

Rending do not count as AP2 for penetrating results! Oh! Ymgarls don't like this!

Q: If an attack with the Rending special rule rolls a 6 for their Armour Penetration roll against a vehicle and subsequently scores a Penetrating Hit, does that hit count as being AP2 as it would if the attack rolled a 6 To Wound? (p41)

A: No.

Chariots cannot sweep our swooping tyrants! Great!

Q: Can the rider of a Chariot that is also a Skimmer make Sweep Attacks against Zooming Flyers or Swooping Flying Monstrous Creatures? (p82).

A: No.

And just a fun thing about paladins:

Q: If a unit of models that are Psykers and armed with force weapons are affected by the You! You’re a Traitor! result of the Hallucination psychic power from the Telepathy discipline, does this force them to spend warp charge points (if they have any available) and activate their force weapons for the hits they inflict upon their own unit? (Reference section).

A: Yes.
