Well if you look closely at the front cover of Inferno in the bottom left corner, we have what seems to be a previously never before seen Custodes model. It's right Pauldron is clearly of the Legio Custodes flavour, as is it's gorget, silver face plate and red eyes. It appears to be sporting a Bolter variant, possibly a Combi-weapon.
Only peculiar thing is that he does not seem to be sporting a cone head.
Maybe a Legio Custodes Tactical Squad?
Not many days to go. Be sure to tune in for our regular event coverage starting on the 3rd of February.
