Beneath The Med
Beneath the Med is a solitaire tactical-level game placing you in command of an Italian submarine during WWII. This is the fourth game in the The Hunters series, and covers one of the largest fleets of submarines in the world at the time. You command one of many submarine models available starting in 1940, and look to successfully complete patrols until the armistice in September 1943.
While your mission is to destroy as much Allied shipping and as many Capital ships as possible, players will find it extremely challenging to survive until the Armistice.
