From the release:
This product consists of modular 6 x 6 tiles that can build a multitude of science fiction facilities in space or on the ground. There are 59 tiles (front and back for 118 total). The set includes connective tiles such as hallways, doors, barriers, stairs, hatches, lifts, access tubes, access shafts, and other connective pieces. The set also includes destination tiles such as an armory, a bridge, a cargo room, a command center, a computer room, a cryo room, an engineering/power room, a med lab, a mess hall, a meeting room, personal quarters, and a security room and security scanner. With this many connective and destination tiles, you can construct a vast number of different science fiction locations for use in space or on land. Then deconstruct them and then recombine them for a totally new adventure location in next week’s session!
This product has both a clean version and a rusted version of all the tiles. The clean version is great for a brand new facility or spaceship that was just opened or commissioned. The rusty version works well for an old facility or derelict spacecraft that needs explored by the group. Combining the clean side and the rusty side, you can create a ship or facility that was refurbished in some sections with the clean side while using the rusty side to denote the older sections of the ship or facility.
