The game is a hexagon-based wargame for two players. The player who takes the side of 'the bugs' has a sheet of paper with a copy of the map-board on which he plots out his bug-hive and tunnel system. This player also controls 'the skinnies'. The human player sends in his infantry and tries to dig them out.
