Battleship: Search and Destroy is a free print & play game that combines the Fog of War of classic Battleship with the fleet action of Battleship Express.
The players take alternating turns that are further broken down into a scouting and an attacking phase. Players assign ships to scout for the enemy. Each ship assigned allows one guess on the traditional Battleship grid. The results are either a miss, hit or identified (all of the ships squares have been discovered).
Once a ship is identified by the opponent, he/she may assign ships to attack that ship and try to sink it. Play proceeds until only 1 player has a ship left afloat.
