From publisher blurb:
The Colony 19 product range provides a number of sci-fi/near-future floor tiles that are suitable for use in most RPG's and wargames of that genre. The tiles themselves are scaled at 1" per grid square, and are intended for use with 28/32mm miniatures.
Included in this particular set are nine pages of tiles that can be used to construct larger rooms than those featured in the starter set (with most rooms in this set being split over multiple pages), as can be seen in the preview below.
Note: to make use of this product you will also need the Colony 19 Starter Set
