Forge World have released the Rapier Quad Mortar. Happily it also has 2 mk4 crew as well. Would be great if you could choose the crew / buy seperately.
We also have the Iron Warrior Transfer sheet! Noticeably it has 2 additional flags (which makes me happy as I was not totally sold on the bottom right one). The detail is amazing. Also seeing what else she had in the works at the open day was awesome and an incredible change to the old transfers' details.
Considering the Legio specific ones are coming out we must assume these are for generic / Fan designed Legios.
