Solitaire and 2 Player Submarine Warfare.
It´s 1939. You possess authentic weapons and technology in a thrilling fog of war where every decicion you take may be your last.
A system of rotatable discs defines your encounters with the enemy by storing all the data and reactions.
You fight to stay alive and to fulfill your secret missions. A 63 cm long wooden U-boat is used to store wooden torpedoes and fuel during the game. The deck’s gun ammo is represented by wooden shells of different kinds and stored in a 20-round wooden magazine. All game tokens are made of wood and engraved as well. Burnt wood sets you back in time and deep under the surface of the ocean. You can call a wolfpack to support you or dive deep to avoid attacks while risking that the pressure may crack your hull every second.
You play multiple missions in every chapter and have unique targets each time. Move your ship above a overworld map and choose your path there. Fuel is used to keep on moving or follow your targets and alter the weather and daytime conditions. Support tickets allows you to refill your ammo and fuel or order combat support via radio. If you encounter enemies at the overworld map you start a combat loop which will be ended after you defeated your enemies or managed to escape. After each mission you will update your crew or even buy new technology for your submarine.
