Oups !
Yes, with the "News Posts" options, I hadn't seen I was in the Tyranid section.
So, what about the French Tyranids ?
Any unit considers dangerous terrain as open, and biotitan considers impossible as dangerous.
Broken formation only makes a simple move.
Formations with a synapse unit have 1+ Initiative, do not take a blast marker for being under fire. and get a +1 to rally.
Formations which loose their synapse have 3+ Initiative.
And Independant formations have 2+ Initiative.
Only a formation with synapse or an independant formation can control/contest objectives (any unit in the formation, not just the synapse units).
BTS objective is the destruction of the Supreme Commander formation.
If no Dominatrix, a Tyranid Prince gets SC for free.
AA : no Gargoiles, the AA is granted by a bio-construction. It is place on an objective, like Eldar webway portal.
Range 75cm, 1 attack dice per aerian unit, AA6+ , AA7+ if contested by ennemy, and nothing if controled by ennemy.
Regeneration : on dice per lost point, 1 point healed on a 5+
Can also heal on a Regroup action, like titans do with theirs shields.
Mycetics "drop pods": like SM drop pods, 15cm, AP5+/AC6+ Disrupt
Tunnelers, like in the rulebook 2004.
And the list has about the same structure as Orks (single, double or triple formation, with upgrades).
You can find it (in French)
