• "Normal" - The default ending for Silent Hill 3, and the only ending available on the first playing of the game. Heather revisits Douglas at the amusement park, and after briefly pretending to be possessed and about to kill him she insists the detective call her by her birth name of Cheryl. This is also the only ending discussed in the Konami guide Book Of Lost Memories.

• "Possessed" - After the game is finished once, a "point" system is enabled, in which they player collects "points" by killing creatures (10 points each), taking damage (1 point per attack), and forgiving the "confessor" in the church (1000 points.) After 4000 points have been achieved, the "Possessed" ending follows, in which it is revealed that the wounded Douglas has been murdered, apparently by Heather.

• "Revenge" - After acquiring the unlockable "Heather Beam" weapon and killing at least 30 creatures with it, the "Revenge" ending is enabled. This ending is a continuation of the "UFO" endings of the previous games and it has Heather arrive at her apartment to find Harry Mason alive and drinking tea with the aliens while Silent Hill 2's James Sunderland hides behind a curtain. Heather tells Harry of what has happened, and the enraged protagonist of the first game takes a fleet of UFO's to Silent Hill and blows up the town.
