Broken Sword: The Angel of Death uses both a point and click and direct
control interface. The player guides George Stobbart's movements with a
mouse or keyboard, and Nicole Collard is also a playable character in
selected portions of the game. George must collect objects that can be
used with other collectible objects, parts of the scenery, or other
people in the game world to solve puzzles and progress in the game.
George can engage in dialogue with other characters through conversation
trees to gain hints of what needs to be done to solve the puzzles or to
progress the plot. As in the first three Broken Sword games, the death
of the player character is possible in The Angel of Death.
After the events in The Sleeping Dragon, George Stobbart is running a
bail bonds office in New York with his partner Virgin. George meets
Anna Maria, a girl with an old manuscript who wants his help to decode
it. A group of mobsters after the manuscript ransack Anna Maria's hotel
room, as well as George's bail bonds office, and steal the manuscript.
George discovers that the mobsters are led by Fingers Martino, who runs
an old meat packing factory. George sneaks into the factory and
overhears a conversation between Fingers and Mr. Spallacci, who has
obtained the manuscript. George manages to covertly take back the
manuscript, which he examines with Anna Maria. George figures out that
the fortified city on it must be Istanbul.
