As I say in the video, each set contains 24 sheets (12 of each page), and contains all the textures to make the tiles themselves...
...as well as a few pieces of scatter terrain to act as barricades, objective markers, or whatever else you can think of ;)
So, if you've been thinking of making a few of the sci-fi tiles, but don't have a printer (or don't want the hassle of printing them yourself), then hopefully these will help :)
You can pick them up for just £4 (+P&P) from the SquareHex website HERE.
(note that you can also get some of the dungeon starter kit HERE and a whole bunch of accessory pieces HERE).
