So I managed to make it out to the 40Kegger Apocalypse game and had the opportunity to field all three biotitans. While they attracted a ridiculous amount of firepower and were all dead by the last turn I was very pleased, especially with the Hierophant shooting a Storm Raven out of the sky and destroying a Shadowsword with rear armour shots in one round. All in all a fun time.
The paint job on the Hierophant is about 60% done but it was painted well enough to take the field. After all, I had been waiting to field this army for a while now. It is taking longer to paint this guy compared to the Hierodules due to the lack of texture on the armour surfaces (even the FW parts). Still it is starting to show what it will look like after it is done. Here is a WIP shot and a couple of the army I fielded in the Apoc game.
