Subtilla

Subtilla is a two-player, head-to-head naval battle game. Each player has a sub, five boats, and a base on his side of the board. A player wins by either destroying all five of the opponent's boats, or by occupying both spaces of the opponent's base at the end of the opponent's turn.

Battles between ships involve dice-rolling, and the subs have special stealth, movement, and torpedo rules.
