Spotted this today, GW posted images talking about scenery and the last picture caught my eye while they was discussing Archeotech Artifacts. It reminds me of the City of Death resin set but it is not from that package (that I may add is out of print and no longer on the GW site). I want to check my stuff tonight but I think this is something new they are about to put out in the next few months. I will post a follow up later!
BTW GW it is Artifacts not Artefacts! I suck as spelling and caught this error.
