Battlefleet Gothic is a spin-off game of the well known Warhammer 40k Universe. It deals with the space combat aspect of the game, and can be integrated fairly seemlessly with the usual tabletop Warhammer 40k. It has much following in Europe, but is underadvertised in the States. It is produced by Games Workshop, and has its own line of books, miniatures, and magazines.
The game uses miniatures of a 1:70 000 scale.
