Darktide comes with nice, sturdy chipboard tokens and markers. Including some two sided ones that represent the blocking terrain and barricades.
I understand why they didn't include plastic terrain: the cost increase would have been ridiculous. But still, the game would be so much more immersive if the terrain was 3D. Luckily, some nice folk on the internets made made some STL files ready to print and paint! The files were inexpensive, and printed well in our plastic filament machine (Mrs. Blackheart used the Prusa Mk.3S and XL).
The addition of the 3D elements really do improve the look and feel of the game. So much so, the next post will be all about this side of the hobby.
