This affects everyone, so make sure you print out the FAQs that affect you: the one for the main rulebook, plus the ones for any codexes you have.
There are many potentially big changes, depending on the units you have!
- Look Out Sir now affects the *closest* model to your Independent Character, not any character within 6″
- Jet Bikes now have the Very Bulky special rule (will have to look this up!)
- “Models equipped with assault grenades don’t suffer the penalty to their Initiative for charging enemies through difficult terrain.”
There’s also these (I think these have come up in recent games, plus there are a few things that might come up):
Q: Can the BS1 of a ever be modified by special rules that modify the BS of a model’s Shooting attack (such as Tau markerlights, Space Marine Signums or Sergeant Telion’s Voice of Experience)? (p13)
Q: Do models that ignore when moving or charging still fight at Initiative step 1 if they charge through difficult terrain?
Q: Can be placed on the upper floors of ruins and similar terrain? (p121)
A: Yes, but not a fortification.
Q: If passengers disembark from a that has suffered a or result, do they still suffer these effects in their next Shooting phase? (p80)
Q: If a unit disembarks from a during the enemy turn, can it in the Assault phase of its own turn? (p80)
A: No, unless the vehicle in question was an Assault Vehicle.
So read through them! I know most of us are still getting used to the new rules, but these are some biggies.
