Decklaration of War: Trench Shock is a World War I themed game where two players deploy troops, weapons, build fortifications, and strategize to defeat their opponent. Victory is reached in one of two ways: by eliminating all the opponent's troops and weapons in No Man's Land. Or destroying all fortifications and soldiers in the opponent's trench. A Round includes three phases, performed in the following sequence, Initiative, Action, and Reinforce. The initiative phase determines which play goes first during the Action phase. During the action phase, each player performs 8 steps: deploying weapons, moving soldiers, attacking, building fortifications, and drawing event cards. Once one player completes the action phase, then it is the next player's turn. The final step is to reinforce for the next round. The game focuses on getting the right dice roll combination to implement your strategy to achieve victory. However, it won't be easy because your opponent is doing the same and taking steps to counteract your plan. Do you have the skill and luck to defeat your opponent? Or will they outwit you and claim victory?
