Heavy Space Marine Captain:
The new multipart Flayed Ones - these are stunning but a real ball-ache to assemble!
Chronomancer - lovely model which comes across 2 wee sprues
All the new terrain:
The rulebook - please note that you actually need the core Rulebook to be able to use this. It does, however, include all the newer unit rules for the models in Indomitus (for both factions). There are also new rules for different dynasties and some new missions. The only thing I would have liked to have been included is a more apparent explanation of the terrain - I know the names but no idea what they do...
Here are the new objective cards too - going to have a better look when we have a game on Tuesday night.
Here is the new double sided board. This is great to really flesh-out what the inside of Necron structures may actually look like. I think I will try to make some of these and walls from plastic card in the future.
