One thing guys, I was thinking looking at wh40K wiki, they have for tyranids an explanation that doesn't mach with battlefleet gothic, but indeed It is good.
The ship in question is the Narval, it is supposed to be a short of worm hole opener, meaning tyranids don't have warp travel but something a bit less fast.
Well I didn't like it at the beginning specially the stupid idea that using a gravitational worm-hole would produce earthquakes in the planet.
But if we just erase that it would mach well, as tyranids ships doesn't have shields they cannot warp travel, indeed Dominus Astra(if I remember well) killed Behemoth's planet devourer(mature central hive ship) detonating it warp drives.
But anyways I will rewrite the definition and the background of the ship this week end and if people like it we can vote
Narvals in concept have no abilities or weapons in game, but can be used as transport in a transport mission.
Concerning defenses I have been thinking and there is no sense in creating rules for static defenses for tyranids but if tyranids defenses were terrain? That would be very interesting and would make tynanids unique.
Ideas I am thinking and actually I will post photos soon.
Kraken nidus or krakens eggs clouds- Krakens are no just void adapted creatures, but are the only non-complex tyranid organism with BFG size to be a ship, well the thing is that it could work as a terrain piece just like minefields but of course paying a lot more points.Or if you think it is so much we can consider just an attack ship cloud or boths as options
Of course we cannot forget mine fields as spore fields.
Now I am thinking on the concept of babysitting ships.
As during the travel tyranids fleets are not active, there could be some kind of ship witch consume more energy but remains active to protect the hole fleet.
that would be a really good opportunity not just for including new ships but also to change tyranids missions list.
I really think they should play also missions like transport missions being defender.
For example using the narvals, or better, using inactive ships as transports to be defended,(As in concept is what bigger ships are, biomass transports)
Don't know, What do the "volks" think?
