The Hunter looks ok. It would be nice if the Predator comes with beefed up armour just like that.
The Centurions still look weird, but not as bad as the Imperial Fist ones with the drills. Did Matt Ward write the rules for these?
Chaplain looks sweet. The Librarian looks like he ha spink eye. The Captain looks like a kit bash using the Captain model from Black Reach and Sicarius' head.
