Halloween: The Game features three distinct endings, each depicting a different escape route for Michael Myers, and reaching them all requires multiple playthroughs since each demands specific in-game actions. A guide from Destructoid outlines how players can trigger each escape sequence, noting that regardless of which ending is achieved, the outcome remains the same: Michael always gets away, with no alternative endings resulting in his capture or death.

The three endings are the Sewer Tunnel, the Railroad, and an escape via the fields. The Sewer Tunnel ending is reached by heading north then west, navigating past police officers to a fenced entrance that can be pried open. The Railroad ending requires players to stick to the left side of the map in the final chapter, avoiding detection by Dr Loomis, then reach the train tracks before a timer expires and head to red lights to trigger the cutscene. The fields ending is triggered by staying to the right of the map early in the game, though the guide's author notes they have not personally achieved this outcome.
