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 are:
A-frame style door assemblies that can be used in conjunction with any of the tiles in the Colony 19 range (or any other tile-set for that matter) - note that these particular doors are the same as those featured in the previous C19 sets.
Closed doorway counters/tokens (for use with the C19 range of tiles)
Open doorway counters/tokens (for use with the C19 range of tiles)
Glass partition/window tokens (for use with the C19 range of tiles)
