The Tabletop Tyrant site has a scan of the 40K Grey Knights Codex cover as well as some rumoured details of the first wave of releases for the army.
Looks like they’ve been taken down.
I can still see it.
Just skip clicking on the links – they take you some place that is mostly unrelated.
There’s a much better version on the Beasts of War site:
That Dreadknight is huge! Makes me want to make an Aliens-inspired diorama with a large ‘Nid beastie, too.
They replaced the version they pinched fromTabletop Tyrant with the one from the GW site this morning.
Not really digging that cover. Looks sort of generic and uninspired. Doesn’t evoke the “most holy warriors of the Emperor” thing I would expect from the Grey Knights.
