Subterrain Strategy is an open-world adventure game with game mechanics taken from chess. Utilizing the strategy used to play chess, the game absorbs the player in a vast cave full of loot and enemies. The goal of the game is to locate and capture the white king. The game targets people who enjoy strategic and puzzle-based games. The world utilizes the special classes of chesspieces to create informal “levels” in the world. For instance, the king is kept in a chamber that can only be accessed through a straight and a diagonal corridor. This ensures that the piece that combats the king must be a queen or a king due to the queen and king being the only pieces that can go forward and diagonal. The player interacts with the world by moving their chess pieces throughout the cave. If the player’s king is captured by a white character, the game ends. The game was built in unity using a series of three-dimensional models developed in Blender. The enemies are programmed to move closer to the player when the player is within a certain range. The player moves by selecting the piece they want to move and then clicking on the tile they want to move to.
