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 free download is a single room that can be used in conjunction with the other tiles in the Colony 19 range.
Note that this download is intended as an example piece (so you can preview the style of the artwork before you buy any of the main tile-sets) and also as a free (single page) expansion tile for the Colony 19 range.
