Man I wonder if some of the new guys will survive the war of beast and witness the deaths of the old veterans.
If they turn up they won't be recognized as tyranids until M.41. It's a bit like the Fenrisan Kraken or the Catachan Devil, creatures that are now believed to be tyranids from an ancient hive fleet that settled in our galaxy. We wouldn't know that necrons are necrons either.
Necrons could be a thing since technically there were some during the Great Crusade awakening, but Nids is a big no no. See IG reply.
Hoping that Alderson can take some of the enemy ships with him to the grave with a full flush of all his weapons.
Actually got teared up eyes there - not even lying. Only thing is he is diverting the Boiling Blood to be not crushed, the Iron Liberator keeps going straight, rams the Ferrus Hammer and then collides into Golbez Fortress below.
Update comes tomorrow, sorry for delay but I want to give especially @TechCaptain and @matt23 a proper post and I am too tired from my wedding anniversary. Will be most likely tomorrow around this time - sorry for delay again!
Though Claudius will more than likely meet his end, I look forward to a fight with a daemon Prince. Y.O.L.F.T.E.O. (You Only Live For The Emperor Once) lol
