Battlefleet Gothic is a tabletop miniatures game based in Games Workshop's Warhammer 40,000 Universe. Wheras Warhammer 40,000 takes place on the surface of a planet Battlefleet Gothic is set in space. Players select spaceships from a variety of fleets, representative of the various Warhammer 40,000 races, up to an agreed points value and these are represented by 2-10cm long models. They then manouvre them according to the ships' movement abilities and roll dice to determine hits according to the specified shooting abilities.

The game is supported by Games Workshop's specialist games division, which periodically releases new rules for the game through the specialist games website (http://www.specialist-games.com/battlefleetgothic/default.htm). The game is intended for older wargamers, aged 16 and up.
