Hector: Badge of Carnage - Full Series is a three-part adventure game for Windows that follows the story of Hector, a detective with unconventional methods. The game's story is split into episodes that were released as separate titles, but it has a single plot where Hector investigates a case that requires his unique skills.

In the game, Hector negotiates with a terrorist who took hostages, and to free them, he must complete quests around the town. The game's humor is evident in these missions, which include fixing the town clock and shutting down a pornography store. Due to this humor, the game is not suitable for children.

Hector features point-and-click gameplay with a heavy focus on dialogues and less on puzzle-solving. Choosing the right lines in dialogues is crucial to completing quests, as Hector can solve almost any problem by talking to other characters in a suitable manner. While not all solutions in the game are obvious, you don't have many items to use, so the variations of your actions are quite limited.
