Raiders of the Deep: U-boats of the Great War, 1914-18 is a board game released in 2018 for 1 player, 120 minutes per game, and ages 12 and up. It was designed by Ian B. Cooper and its main mechanics are Push Your Luck, Dice Rolling, and Paper-and-Pencil.
Raiders of the Deep: U-boats of the Great War, 1914-18 is a new game inspired by Gregory Smith's The Hunters: German U-Boats at War, 1939-43 that places the player in command of a German U-boat during WWI. Completely re-written rules and reworked charts simulate all the major aspects of the First U-boat War, while all-new artwork immerses the player in the atmosphere of the period. Your mission is to destroy as much entente shipping and as many capital ships as possible, while advancing your crew quality, winning awards and increasing your commander rank - all while attempting to make it home amidst diminishing odds of survival as the war progresses. Conducting patrols is the heart of the system: each game turn you will resolve encounters against individual ships, convoys, Q-ships and enemy aircraft. Situations you will face will demand decisions such as... How will you engage a convoy? Do you risk closing range for a potentially more lethal attack? If the engagement is at night, will you conduct a surface attack? With ammunition dwindling, will you try to follow a convoy, or will you look for easier targets? Every decision you make during the U-boat war determines whether you and your crew come home as heroes, failures - or not at all. The game was designed by a ten year BGG veteran and was developed and playtested with the help of the U-boat game aficionados in the BGG community.
