Sam & Max 203: Night of the Raving Dead is a parody adventure game, developed by Telltale Games. The game is set in a 3D universe where New York's streets are filled with dancing zombies, and Sam and Max are the Freelance Police. The objective of the game is to kill all the zombies and confront their leader, a European vampire. The game is based on Steve Purcell's comic series, and the characters try to find a resolution in Stuttgart, Germany.

In the game, the player controls Sam and Max, who are detectives. The gameplay involves solving puzzles and completing various tasks. The game has branching dialogues that let the player make decisions, choosing between the given options. The game is a parody of classic vampire stories like Frankenstein and stereotypes about Germans, lacking any sense of humor. The dialogues between characters have the usual TellTale sense of humor, and there are some plot twists. The game also has jazz soundtracks that complement the game's mood.
