Richard, Duke of Gloucester, has imprisoned Edward V and his brother Richard, Duke of York, in the Tower of London and plans to have himself be crowned King. In the alternate history game 1483 Anno Domini, players control Sir Arcyus, who is asked by people loyal to Edward V to free the two young royals from their prison cell and prevent Richard III's coronation. Almost 20 buildings of the Tower of London can be chosen from an authentic map, and explored in grid-based 3D first-person view. Gameplay revolves mostly around exploration, conversation, and inventory-based puzzles. However, certain problems can only be solved in combat. When insulting or directly attacking an opponent, the game switches to a real-time swordfighting minigame.
